A, C, I Shares | JPMorgan SmartRetirement Income Fund

<b>JPMorgan SmartRetirement^® Income Fund<br/>Class/Ticker: A/JSRAX; C/JSRCX; I/JSRSX</b>

<b>What is the goal of the Fund? </b>

The Fund seeks current income and some capital appreciation.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 96 and in “Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement Income Fund	Class A		Class C	Class I
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	4.50%		none	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES<br/> (Expenses that you pay each year as a percentage of the value<br/> of your investment)</b>

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement Income Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	521	722	940	1,565
CLASS C SHARES	238	452	788	1,738
CLASS I SHARES	62	215	381	862

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/> WOULD BE: </b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement Income Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	521	722	940	1,565
CLASS C SHARES	138	452	788	1,738
CLASS I SHARES	62	215	381	862

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® Income Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors who are retired or about to retire soon. The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, with an emphasis on fixed income funds over equity funds and other funds. The Fund’s strategic target allocations among various asset and sub-asset classes as of November 1, 2018 are set forth below:

Strategic Target Allocations1
Fixed Income	59.0%
U.S. Fixed Income Funds	37.5%
Inflation Managed Funds	9.0%
High Yield Funds	9.1%
Emerging Markets Debt Funds	3.4%
Equity	36.0%
U.S. Large Cap Equity Funds	15.8%
U.S. Small/Mid Cap Equity Funds	3.7%
REIT Funds	2.2%
International Equity Funds	10.8%
Emerging Markets Equity Funds	3.6%
Money Market/Cash and Cash Equivalents	5.0%
Money Market Funds/Cash and Cash Equivalents	5.0%
Commodities	0.0%
Commodities Funds	0.0%

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The table above shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date Retirement Income Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments listed above. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed above from time to time.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date Retirement Income Index, a broad-based securities market index, and the Lipper Mixed-Asset Target Today Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.31%, 0.94% and 0.19% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® Income Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors who are retired or about to retire soon. The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, with an emphasis on fixed income funds over equity funds and other funds. The Fund’s strategic target allocations among various asset and sub-asset classes as of November 1, 2018 are set forth below:

Strategic Target Allocations1
Fixed Income	59.0%
U.S. Fixed Income Funds	37.5%
Inflation Managed Funds	9.0%
High Yield Funds	9.1%
Emerging Markets Debt Funds	3.4%
Equity	36.0%
U.S. Large Cap Equity Funds	15.8%
U.S. Small/Mid Cap Equity Funds	3.7%
REIT Funds	2.2%
International Equity Funds	10.8%
Emerging Markets Equity Funds	3.6%
Money Market/Cash and Cash Equivalents	5.0%
Money Market Funds/Cash and Cash Equivalents	5.0%
Commodities	0.0%
Commodities Funds	0.0%

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The table above shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date Retirement Income Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

Risk [Heading]

rr_RiskHeading

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments listed above. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed above from time to time.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.31%, 0.94% and 0.19% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] On 6/1/17, the methodology used to calculate the S&P Target Date Retirement Income Index was changed. Prior to 6/1/17, the S&P Target Date Retirement Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date Retirement Index is comprised of underlying indices of securities.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in "Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION" on page 96 and in "Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in "PURCHASES, REDEMPTIONS AND EXCHANGES" in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2020 Fund	Class A		Class C	Class I

"Acquired Fund (Underlying Fund) Fees and Expenses" are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund's net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2020 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	529	732	952	1,583
CLASS C SHARES	244	461	801	1,762
CLASS I SHARES	67	224	395	889

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/> WOULD BE: </b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2020 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2020 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2020 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2020 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2020 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2020 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.36%, 0.96% and 0.21% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2020 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2020 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2020 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.36%, 0.96% and 0.21% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in "Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION" on page 96 and in "Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in "PURCHASES, REDEMPTIONS AND EXCHANGES" in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2025 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2025 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2025 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 10% for equity, +/- 15% for fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2025 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2025 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2025 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2025 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2025 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 10% for equity, +/- 15% for fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] On 6/1/17, the methodology used to calculate the S&P Target Date 2025 Index was changed. Prior to 6/1/17, the S&P Target Date 2025 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2025 Index is comprised of underlying indices of securities.

<b>JPMorgan SmartRetirement^® 2030 Fund<br/>Class/Ticker: A/JSMAX; C/JSMCX; I/JSMSX</b>

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in "Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION" on page 96 and in "Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in "PURCHASES, REDEMPTIONS AND EXCHANGES" in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2030 Fund	Class A		Class C	Class I
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	4.50%		none	none

"Acquired Fund (Underlying Fund) Fees and Expenses" are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund's net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2030 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	534	741	965	1,607
CLASS C SHARES	248	471	818	1,796
CLASS I SHARES	72	233	408	915

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/>WOULD BE:</b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2030 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years

CLASS C SHARES	148	471	818	1,796
CLASS I SHARES	72	233	408	915

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2030 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2030 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2030 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund's Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2030 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2030 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2030 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2030 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2030 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 96 and in “Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2035 Fund	Class A		Class C	Class I

Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none	[1]	1.00%	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/> (Expenses that you pay each year as a percentage of the value <br/>of your investment)</b>

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2035 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	535	744	970	1,618
CLASS C SHARES	248	476	827	1,817
CLASS I SHARES	72	235	412	926

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/> WOULD BE: </b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2035 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	535	744	970	1,618
CLASS C SHARES	148	476	827	1,817
CLASS I SHARES	72	235	412	926

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2035 Fund is a "fund of funds" that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2035 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund's asset allocation strategy will change. The "glide path" depicted in the chart below shows how the Fund's strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund's long term strategic target allocations as of November 1, 2018. The Fund's actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund's strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2035 Index (the Fund's benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund's strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund's investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund's strategic target allocations shown in the glide path and table above may be different from the Fund's actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser's ability to make these modifications, the Fund's actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund's strategic target allocations and actual allocations to underlying funds and investments is available in the Fund's shareholder reports and on the Fund's website from time to time.

The Fund is a "to" target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund's Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2035 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2035 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2035 Fund is a "fund of funds" that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2035 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund's asset allocation strategy will change. The "glide path" depicted in the chart below shows how the Fund's strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund's long term strategic target allocations as of November 1, 2018. The Fund's actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund's strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2035 Index (the Fund's benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund's strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund's investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund's strategic target allocations shown in the glide path and table above may be different from the Fund's actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser's ability to make these modifications, the Fund's actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund's strategic target allocations and actual allocations to underlying funds and investments is available in the Fund's shareholder reports and on the Fund's website from time to time.

The Fund is a "to" target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund's Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] On 6/1/17, the methodology used to calculate the S&P Target Date 2035 Index was changed. Prior to 6/1/17, the S&P Target Date 2035 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2035 Index is comprised of underlying indices of securities.

<b>JPMorgan SmartRetirement^® 2040 Fund</b> <br/><b>Class/Ticker: A/SMTAX; C/SMTCX; I/SMTSX</b>

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 96 and in “Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2040 Fund	Class A		Class C	Class I

Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none	[1]	1.00%	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2040 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	747	975	1,630
CLASS C SHARES	249	479	832	1,828
CLASS I SHARES	73	238	417	938

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST <br/>WOULD BE: </b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2040 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	747	975	1,630
CLASS C SHARES	149	479	832	1,828
CLASS I SHARES	73	238	417	938

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2040 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2040 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2040 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2040 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2040 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2040 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2040 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2040 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>JPMorgan SmartRetirement^® 2045 Fund</b><br/><b>Class/Ticker: A/JSAAX; C/JSACX; I/JSASX</b>

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 96 and in “Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2045 Fund	Class A		Class C	Class I
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	4.50%		none	none
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none	[1]	1.00%	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/> (Expenses that you pay each year as a percentage of the value <br/>of your investment)</b>

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2045 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	537	750	980	1,641
CLASS C SHARES	250	484	841	1,849
CLASS I SHARES	74	241	423	949

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/> WOULD BE: </b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2045 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	537	750	980	1,641
CLASS C SHARES	150	484	841	1,849
CLASS I SHARES	74	241	423	949

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2045 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2045 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2045 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2045 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2045 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2045 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2045 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2045 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] On 6/1/17, the methodology used to calculate the S&P Target Date 2045 Index was changed. Prior to 6/1/17, the S&P Target Date 2045 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2045 Index is comprised of underlying indices of securities.

<b>JPMorgan SmartRetirement^® 2050 Fund<br/>Class/Ticker: A/JTSAX; C/JTSCX; I/JTSSX</b>

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 96 and in “Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE: </b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2050 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	749	979	1,640
CLASS C SHARES	249	485	845	1,858
CLASS I SHARES	73	240	422	949

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST <br/>WOULD BE: </b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2050 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2050 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2050 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2050 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2050 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2050 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2050 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2050 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2050 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>JPMorgan SmartRetirement^® 2055 Fund</b><br/><b>Class/Ticker: A/JFFAX; C/JFFCX; I/JFFSX </b>

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in "Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION" on page 96 and in "Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in "PURCHASES, REDEMPTIONS AND EXCHANGES" in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2055 Fund	Class A		Class C	Class I

Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none	[1]	1.00%	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2055 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	753	988	1,660
CLASS C SHARES	249	506	888	1,959
CLASS I SHARES	73	242	426	960

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/> WOULD BE:</b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2055 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	753	988	1,660
CLASS C SHARES	149	506	888	1,959
CLASS I SHARES	73	242	426	960

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2055 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2055 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2055 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year over the past five calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. It compares that performance to the S&P Target Date 2055 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2055 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2055 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2055 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] On 6/1/17, the methodology used to calculate the S&P Target Date 2055 Index was changed. Prior to 6/1/17, the S&P Target Date 2055 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2055 Index is comprised of underlying indices of securities.

<b>JPMorgan SmartRetirement^® 2060 Fund<br/> Class/Ticker: A/JAKAX; C/JAKCX; I/JAKSX </b>

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 96 and in “Financial Intermediary-Specific Sales Charge Waivers in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan SmartRetirement 2060 Fund	Class A		Class C	Class I

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example - A, C, I Shares - JPMorgan SmartRetirement 2060 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	897	1,282	2,360
CLASS C SHARES	249	657	1,191	2,655
CLASS I SHARES	73	382	713	1,651

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST<br/> WOULD BE:</b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan SmartRetirement 2060 Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	536	897	1,282	2,360

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2060 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2060 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2060+ Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows the performance of the Fund’s Class A Shares for the past calendar year. The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the S&P Target Date 2060+ Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Index, an index based on the total returns of all mutual funds within the Funds designated category as determined by Lipper. Unlike the S&P Index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information will be available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2060 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2060 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2060+ Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39%, 0.97% and 0.22% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>What is the goal of the Fund?</b>

The Fund seeks current income and some capital appreciation.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example</b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies?</b>

The JPMorgan SmartRetirement^® Income Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors who are retired or about to retire soon. The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, with an emphasis on fixed income funds over equity funds and other funds. The Fund’s strategic target allocations among various asset and sub-asset classes as of November 1, 2018 are set forth below:

Strategic Target Allocations1
Fixed Income	59.0%
U.S. Fixed Income Funds	37.5%
Inflation Managed Funds	9.0%
High Yield Funds	9.1%
Emerging Markets Debt Funds	3.4%
Equity	36.0%
U.S. Large Cap Equity Funds	15.8%
U.S. Small/Mid Cap Equity Funds	3.7%
REIT Funds	2.2%
International Equity Funds	10.8%
Emerging Markets Equity Funds	3.6%
Money Market/Cash and Cash Equivalents	5.0%
Money Market Funds/Cash and Cash Equivalents	5.0%
Commodities	0.0%
Commodities Funds	0.0%

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The table above shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date Retirement Income Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments listed above. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed above from time to time.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date Retirement Income Index, a broad-based securities market index, and the Lipper Mixed-Asset Target Today Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date Retirement Income Index was changed. Prior to 6/1/17, the S&P Target Date Retirement Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date Retirement Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® Income Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors who are retired or about to retire soon. The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, with an emphasis on fixed income funds over equity funds and other funds. The Fund’s strategic target allocations among various asset and sub-asset classes as of November 1, 2018 are set forth below:

Strategic Target Allocations1
Fixed Income	59.0%
U.S. Fixed Income Funds	37.5%
Inflation Managed Funds	9.0%
High Yield Funds	9.1%
Emerging Markets Debt Funds	3.4%
Equity	36.0%
U.S. Large Cap Equity Funds	15.8%
U.S. Small/Mid Cap Equity Funds	3.7%
REIT Funds	2.2%
International Equity Funds	10.8%
Emerging Markets Equity Funds	3.6%
Money Market/Cash and Cash Equivalents	5.0%
Money Market Funds/Cash and Cash Equivalents	5.0%
Commodities	0.0%
Commodities Funds	0.0%

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The table above shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date Retirement Income Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments listed above. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed above from time to time.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date Retirement Income Index, a broad-based securities market index, and the Lipper Mixed-Asset Target Today Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[2] On 6/1/17, the methodology used to calculate the S&P Target Date Retirement Income Index was changed. Prior to 6/1/17, the S&P Target Date Retirement Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date Retirement Index is comprised of underlying indices of securities.

<b>What is the goal of the Fund?</b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies?</b>

The JPMorgan SmartRetirement^® 2020 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2020 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2020 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2020 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2020 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2020 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2020 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2020 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

Risk [Heading]

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

It compares that performance to the S&P Target Date 2020 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2020 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[2] On 6/1/17, the methodology used to calculate the S&P Target Date 2020 Index was changed. Prior to 6/1/17, the S&P Target Date 2020 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2020 Index is comprised of underlying indices of securities.

<b>What is the goal of the Fund?</b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2025 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2025 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2025 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 10% for equity, +/- 15% for fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund's strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund's investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund's Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund's investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund's investments in an underlying fund may create a conflict of interest. In addition, the Adviser's authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund's tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company's financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund's or the underlying fund's portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund's investment decreases in value.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund's exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called "sub-prime" mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for "sub-prime" mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund's securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded "delivery versus payment," an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund's or an underlying fund's original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund's direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund's shares may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2025 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2025 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2025 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2025 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2025 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 10% for equity, +/- 15% for fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund's strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund's investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund's Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund's investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund's investments in an underlying fund may create a conflict of interest. In addition, the Adviser's authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund's tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company's financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund's or the underlying fund's portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund's investment decreases in value.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund's exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called "sub-prime" mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for "sub-prime" mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund's securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded "delivery versus payment," an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund's or an underlying fund's original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund's direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund's shares may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2030 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2030 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2030 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2030 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2030 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

Strategy [Heading]

<b>What are the Fund’s main investment strategies? </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2030 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2030 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2030 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

Risk [Heading]

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2030 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2030 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example</b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 54% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2035 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2035 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2035 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2035 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2035 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 54% of the average value of its portfolio.

Strategy [Heading]

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2035 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2035 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2035 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

Risk [Heading]

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[2] On 6/1/17, the methodology used to calculate the S&P Target Date 2035 Index was changed. Prior to 6/1/17, the S&P Target Date 2035 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2035 Index is comprised of underlying indices of securities.

<b>What is the goal of the Fund?</b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2040 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2040 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2040 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance</b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2040 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2040 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2040 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2040 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2040 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>What is the goal of the Fund?</b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example</b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies?</b>

The JPMorgan SmartRetirement^® 2045 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2045 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2045 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2045 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2045 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who holds their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2045 Index was changed. Prior to 6/1/17, the S&P Target Date 2045 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2045 Index is comprised of underlying indices of securities.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2045 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2045 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2045 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

<b>The Fund’s Past Performance </b>

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2045 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2045 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Prior to 6/1/17, the S&P Target Date 2045 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2045 Index is comprised of underlying indices of securities.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example</b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies?</b>

The JPMorgan SmartRetirement^® 2050 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2050 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2050 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2050 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2050 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R2 Shares and Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R2 Shares and Class R3 Shares. The actual returns of Class R2 Shares and Class R3 Shares would have been different than those shown because Class R2 Shares and Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R6 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2050 Index was changed. Prior to 6/1/17, the S&P Target Date 2050 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2050 Index is comprised of underlying indices of securities.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2050 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2050 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2050 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[2] On 6/1/17, the methodology used to calculate the S&P Target Date 2050 Index was changed. Prior to 6/1/17, the S&P Target Date 2050 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2050 Index is comprised of underlying indices of securities.

<b>What is the goal of the Fund?</b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example</b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2055 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2055 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2055 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year over the past five calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. It compares that performance to the S&P Target Date 2055 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R3 Shares is based on the performance of Class A Shares (which are not offered in this prospectus) prior to the inception of Class R3 Shares. The actual returns of Class R3 Shares would have been different than those shown because Class R3 Shares have different expenses than Class A Shares. The performance of Class R4 Shares is based on the performance of Class I Shares (which are not offered in this prospectus) prior to the inception of Class R4 Shares. The actual returns of Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. The performance of Class R6 Shares is based on the performance of Class R5 Shares prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Strategy [Heading]

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2055 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2055 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2055 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

<b>What is the goal of the Fund?</b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund</b>

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Portfolio Turnover</b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies?</b>

The JPMorgan SmartRetirement^® 2060 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2060 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2060+ Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows the performance of the Fund’s Class R2 Shares for the past calendar year. The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the S&P Target Date 2060+ Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Index, an index based on the total returns of all mutual funds within the Funds designated category as determined by Lipper. Unlike the S&P Index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Returns for Class R3 Shares prior to their inception date are based on the performance of Class A Shares (which are not offered in this prospectus). The actual returns for Class R3 Shares would have been different than those shown because Class R3 Shares have different expenses than Class A Shares. Returns for Class R4 Shares prior to their inception date are based on the performance of Class I Shares (which are not offered in this prospectus). The actual return for Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

After-tax returns are shown only for the Class R2 Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2060+ Index was changed. Prior to 6/1/17, the S&P Target Date 2060+ Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2060+ Index is comprised of underlying indices of securities.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2060 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2060 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2060+ Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the S&P Target Date 2060+ Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Index, an index based on the total returns of all mutual funds within the Funds designated category as determined by Lipper. Unlike the S&P Index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Returns for Class R3 Shares prior to their inception date are based on the performance of Class A Shares (which are not offered in this prospectus). The actual returns for Class R3 Shares would have been different than those shown because Class R3 Shares have different expenses than Class A Shares. Returns for Class R4 Shares prior to their inception date are based on the performance of Class I Shares (which are not offered in this prospectus). The actual return for Class R4 Shares would have been different than those shown because Class R4 Shares have different expenses than Class I Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.75%, 0.50%, 0.25%, 0.10% and 0.00% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[2] On 6/1/17, the methodology used to calculate the S&P Target Date 2060+ Index was changed. Prior to 6/1/17, the S&P Target Date 2060+ Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2060+ Index is comprised of underlying indices of securities.

T Shares | JPMorgan SmartRetirement Income Fund

<b>JPMorgan SmartRetirement^® Income Fund <br/>Class/Ticker: T/* </b><br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks current income and some capital appreciation.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 92 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees	T Shares JPMorgan SmartRetirement Income Fund Class T
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	2.50%
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES<br/>(Expenses that you pay each year as a percentage of the value<br/> of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement Income Fund Class T
Management Fees	none
Distribution (Rule 12b-1) Fees	0.25%
Other Expenses	0.28%
Service Fees	0.25%
Remainder of Other Expenses	0.03%	[1]
Acquired Fund (Underlying Fund) Fees and Expenses	0.44%	[1]

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement Income Fund | CLASS T SHARES | USD ($)	323	528	750	1,389

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement Income Fund | CLASS T SHARES | USD ($)	323	528	750	1,389

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® Income Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors who are retired or about to retire soon. The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, with an emphasis on fixed income funds over equity funds and other funds. The Fund’s strategic target allocations among various asset and sub-asset classes as of November 1, 2018 are set forth below:

Strategic Target Allocations1
Fixed Income	59.0%
U.S. Fixed Income Funds	37.5%
Inflation Managed Funds	9.0%
High Yield Funds	9.1%
Emerging Markets Debt Funds	3.4%
Equity	36.0%
U.S. Large Cap Equity Funds	15.8%
U.S. Small/Mid Cap Equity Funds	3.7%
REIT Funds	2.2%
International Equity Funds	10.8%
Emerging Markets Equity Funds	3.6%
Money Market/Cash and Cash Equivalents	5.0%
Money Market Funds/Cash and Cash Equivalents	5.0%
Commodities	0.0%
Commodities Funds	0.0%

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The table above shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date Retirement Income Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments listed above. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed above from time to time.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date Retirement Income Index, a broad-based securities market index, and the Lipper Mixed-Asset Target Today Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

<b>YEAR-BY-YEAR RETURNS — CLASS A SHARES</b>

Best Quarter	2nd quarter, 2009	9.99%
Worst Quarter	4th quarter, 2008	-7.94%

The Fund’s year-to-date total return through 9/30/18 was 0.35%.

<b>AVERAGE ANNUAL TOTAL RETURNS <br/>(For periods ended December 31, 2017)</b>

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.31% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date Retirement Income Index was changed. Prior to 6/1/17, the S&P Target Date Retirement Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date Retirement Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® Income Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors who are retired or about to retire soon. The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, with an emphasis on fixed income funds over equity funds and other funds. The Fund’s strategic target allocations among various asset and sub-asset classes as of November 1, 2018 are set forth below:

Strategic Target Allocations1
Fixed Income	59.0%
U.S. Fixed Income Funds	37.5%
Inflation Managed Funds	9.0%
High Yield Funds	9.1%
Emerging Markets Debt Funds	3.4%
Equity	36.0%
U.S. Large Cap Equity Funds	15.8%
U.S. Small/Mid Cap Equity Funds	3.7%
REIT Funds	2.2%
International Equity Funds	10.8%
Emerging Markets Equity Funds	3.6%
Money Market/Cash and Cash Equivalents	5.0%
Money Market Funds/Cash and Cash Equivalents	5.0%
Commodities	0.0%
Commodities Funds	0.0%

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The table above shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date Retirement Income Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments listed above. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed above from time to time.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.31% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

<b>JPMorgan SmartRetirement^® 2020 Fund<br/>Class/Ticker: T/*</b><br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in "Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION" on page 92 of the prospectus and in "PURCHASES, REDEMPTIONS AND EXCHANGES" in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

"Acquired Fund (Underlying Fund) Fees and Expenses" are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES<br/> (Expenses that you pay each year as a percentage of the value<br/> of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement 2020 Fund Class T

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2020 Fund | CLASS T SHARES | USD ($)	331	538	762	1,406

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2020 Fund | CLASS T SHARES | USD ($)	331	538	762	1,406

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2020 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2020 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2020 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2020 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2020 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

<b>YEAR-BY-YEAR RETURNS — CLASS A SHARES</b>

Best Quarter	2nd quarter, 2009	15.58%
Worst Quarter	4th quarter, 2008	-15.68%

The Fund’s year-to-date total return through 9/30/18 was 0.71%.

<b>AVERAGE ANNUAL TOTAL RETURNS <br/>(For periods ended December 31, 2017)</b>

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.36% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2020 Index was changed. Prior to 6/1/17, the S&P Target Date 2020 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2020 Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2020 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2020 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2020 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for fixed income, +/- 10% for equity, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[4] On 6/1/17, the methodology used to calculate the S&P Target Date 2020 Index was changed. Prior to 6/1/17, the S&P Target Date 2020 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2020 Index is comprised of underlying indices of securities.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2025 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2025 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2025 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 10% for equity, +/- 15% for fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2025 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2025 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2025 Index was changed. Prior to 6/1/17, the S&P Target Date 2025 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2025 Index is comprised of underlying indices of securities.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2025 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2025 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2025 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 10% for equity, +/- 15% for fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2025 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2025 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

T Shares | JPMorgan SmartRetirement 2030 Fund

<b>JPMorgan SmartRetirement^® 2030 Fund <br/>Class/Ticker: T/* </b><br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 92 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees	T Shares JPMorgan SmartRetirement 2030 Fund Class T
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	2.50%
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES<br/>(Expenses that you pay each year as a percentage of the value<br/>of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement 2030 Fund Class T
Management Fees	none
Distribution (Rule 12b-1) Fees	0.25%
Other Expenses	0.27%
Service Fees	0.25%
Remainder of Other Expenses	0.02%	[1]

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2030 Fund | CLASS T SHARES | USD ($)	336	547	775	1,432

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2030 Fund | CLASS T SHARES | USD ($)	336	547	775	1,432

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2030 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2030 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2030 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2030 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2030 Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

<b>YEAR-BY-YEAR RETURNS — CLASS A SHARES</b>

Best Quarter	2nd quarter, 2009	18.46%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2030 Index was changed. Prior to 6/1/17, the S&P Target Date 2030 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2030 Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2030 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2030 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2030 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.38% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

T Shares | JPMorgan SmartRetirement 2035 Fund

<b>JPMorgan SmartRetirement^® 2035 Fund</b> <br/><b>Class/Ticker: T/*</b><br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 92 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees	T Shares JPMorgan SmartRetirement 2035 Fund Class T
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	2.50%
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/>(Expenses that you pay each year as a percentage of the value<br/> of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement 2035 Fund Class T
Management Fees	none
Distribution (Rule 12b-1) Fees	0.25%
Other Expenses	0.27%
Service Fees	0.25%
Remainder of Other Expenses	0.02%	[1]

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2035 Fund | CLASS T SHARES | USD ($)	337	550	781	1,443

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2035 Fund | CLASS T SHARES | USD ($)	337	550	781	1,443

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2035 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2035 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2035 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2035 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2035 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

<b>YEAR-BY-YEAR RETURNS — CLASS A SHARES </b>

Best Quarter	2nd quarter, 2009	19.32%
Worst Quarter	4th quarter, 2008	-19.28%

The Fund’s year-to-date total return through 9/30/18 was 1.65%.

<b>AVERAGE ANNUAL TOTAL RETURNS<br/> (For periods ended December 31, 2017)</b>

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2035 Index was changed. Prior to 6/1/17, the S&P Target Date 2035 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2035 Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2035 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2035 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2035 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[4] On 6/1/17, the methodology used to calculate the S&P Target Date 2035 Index was changed. Prior to 6/1/17, the S&P Target Date 2035 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2035 Index is comprised of underlying indices of securities.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2040 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2040 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2040 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2040 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2040 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2040 Index was changed. Prior to 6/1/17, the S&P Target Date 2040 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2040 Index is comprised of underlying indices of securities.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2040 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2040 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2040 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

T Shares | JPMorgan SmartRetirement 2045 Fund

<b>JPMorgan SmartRetirement^® 2045 Fund <br/>Class/Ticker: T/* </b><br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 92 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees	T Shares JPMorgan SmartRetirement 2045 Fund Class T
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	2.50%
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/> (Expenses that you pay each year as a percentage of the value <br/>of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement 2045 Fund Class T

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2045 Fund | CLASS T SHARES | USD ($)	339	556	791	1,466

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

T Shares | JPMorgan SmartRetirement 2045 Fund | CLASS T SHARES | USD ($)	339	556	791	1,466

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2045 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2045 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2045 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2045 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2045 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

<b>YEAR-BY-YEAR RETURNS — CLASS A SHARES </b>

Best Quarter	2nd quarter, 2009	19.13%
Worst Quarter	4th quarter, 2008	-19.29%

The Fund’s year-to-date total return through 9/30/18 was 2.07%.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2045 Index was changed. Prior to 6/1/17, the S&P Target Date 2045 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2045 Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2045 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2045 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2045 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

T Shares | JPMorgan SmartRetirement 2050 Fund

<b>JPMorgan SmartRetirement^® 2050 Fund <br/>Class/Ticker: T/*</b> <br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 92 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees	T Shares JPMorgan SmartRetirement 2050 Fund Class T
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	2.50%
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/> (Expenses that you pay each year as a percentage of the value<br/> of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement 2050 Fund Class T
Management Fees	none
Distribution (Rule 12b-1) Fees	0.25%
Other Expenses	0.28%
Service Fees	0.25%
Remainder of Other Expenses	0.03%	[1]
Acquired Fund (Underlying Fund) Fees and Expenses	0.50%	[1]

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2050 Fund | CLASS T SHARES | USD ($)	338	555	790	1,465

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2050 Fund | CLASS T SHARES | USD ($)	338	555	790	1,465

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2050 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2050 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2050 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance</b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. It compares that performance to the S&P Target Date 2050 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2050 Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

<b>YEAR-BY-YEAR RETURNS — CLASS A SHARES </b>

Best Quarter	2nd quarter, 2009	19.00%
Worst Quarter	4th quarter, 2008	-19.17%

The Fund’s year-to-date total return through 9/30/18 was 2.03%.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2050 Index was changed. Prior to 6/1/17, the S&P Target Date 2050 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2050 Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2050 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2050 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2050 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITS are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund's investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[4] On 6/1/17, the methodology used to calculate the S&P Target Date 2050 Index was changed. Prior to 6/1/17, the S&P Target Date 2050 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2050 Index is comprised of underlying indices of securities.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2055 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2055 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2055 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance </b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past five calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. It compares that performance to the S&P Target Date 2055 Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Average, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2055 Index was changed. Prior to 6/1/17, the S&P Target Date 2055 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2055 Index is comprised of underlying indices of securities.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2055 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2055 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2055 Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows how the performance of the Fund’s Class A Shares (which are not offered in this prospectus) has varied from year to year for the past five calendar years.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[4] On 6/1/17, the methodology used to calculate the S&P Target Date 2055 Index was changed. Prior to 6/1/17, the S&P Target Date 2055 Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2055 Index is comprised of underlying indices of securities.

T Shares | JPMorgan SmartRetirement 2060 Fund

<b>JPMorgan SmartRetirement 2060 Fund<br/>Class/Ticker: T/* </b><br/><br/>^* The share class is currently not offered to the public.

<b>What is the goal of the Fund? </b>

The Fund seeks high total return with a shift to current income and some capital appreciation over time as the Fund approaches and passes the target retirement date.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class T Shares if you invest at least $250,000 in the Fund. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 92 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees	T Shares JPMorgan SmartRetirement 2060 Fund Class T
Maximum Sales Charge (Load) Imposed on Purchases as % of Offering Price	2.50%
Maximum Deferred Sales Charge (Load) as % of Original Cost of the Shares	none

“Acquired Fund (Underlying Fund) Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund (Underlying Fund) Fees and Expenses is included in the total returns of the Fund. Acquired Fund (Underlying Fund) Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/>(Expenses that you pay each year as a percentage of the value <br/>of your investment)</b>

Annual Fund Operating Expenses	T Shares JPMorgan SmartRetirement 2060 Fund Class T
Management Fees	none
Distribution (Rule 12b-1) Fees	0.25%
Other Expenses	1.02%
Service Fees	0.25%
Remainder of Other Expenses	0.77%	[1]

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2060 Fund | CLASS T SHARES | USD ($)	338	707	1,100	2,200

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
T Shares | JPMorgan SmartRetirement 2060 Fund | CLASS T SHARES | USD ($)	338	707	1,100	2,200

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The JPMorgan SmartRetirement^® 2060 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2060 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2060+ Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance</b>

This section provides some indication of the risks of investing in the Fund. Because Class T Shares have not yet commenced operations as of the date of this prospectus, the bar chart shows the performance of the Fund’s Class A Shares (which are not offered in this prospectus) for the past calendar year. The table shows the average annual total returns for the past one year and life of the Fund. It compares that performance to the S&P Target Date 2060+ Index, a broad-based securities market index, and the Lipper Mixed-Asset Target 2055+ Funds Index, an index based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the S&P indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[1] The performance of Class T Shares would be substantially similar to the performance of Class A Shares because the Fund is invested in the same group of securities and the annual returns would differ only to the extent that the classes do not have the same expenses.

[1] On 6/1/17, the methodology used to calculate the S&P Target Date 2060+ Index was changed. Prior to 6/1/17, the S&P Target Date 2060+ Index was comprised of ETFs, adjusted to remove the impact of ETF fees. Effective 6/1/17, the S&P Target Date 2060+ Index is comprised of underlying indices of securities.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The JPMorgan SmartRetirement^® 2060 Fund is a “fund of funds” that primarily invests in other mutual funds within the same group of investment companies, and is generally intended for investors expecting to retire around the year 2060 (target retirement date). The Fund is designed to provide exposure to a variety of asset classes through investments in underlying funds, and over time the Fund’s asset allocation strategy will change. The “glide path” depicted in the chart below shows how the Fund’s strategic target allocations among asset and sub-asset classes generally become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity). The table accompanying the chart is simply the glide path in tabular form.

Note: Above allocations may not sum up to 100% due to rounding.

1 As of 11/1/18, the Fund utilizes mutual funds and, to a lesser extent, exchange-traded funds (ETFs) to implement its strategic target allocations although the Fund also has flexibility to utilize other direct investments in securities and derivatives to implement its strategic target allocations in the future.

The glide path shows the Fund’s long term strategic target allocations as of November 1, 2018. The Fund’s actual allocations may differ due to changes to these strategic target allocations or due to tactical allocations. In establishing the Fund’s strategic target allocations, the Adviser focuses on asset classes and underlying funds that the Adviser believes will outperform the S&P Target Date 2060+ Index (the Fund’s benchmark) and peer group over the long term. The Adviser will use tactical allocations to take advantage of short to intermediate term opportunities through a combination of positions in underlying funds and direct investments, including derivatives.

The Adviser will review the Fund’s strategic target allocations shown in the glide path at least annually (generally, in the first quarter of each calendar year), and may adjust the targets in its discretion, consistent with the Fund’s investment strategy. These changes might include modifying the existing strategic target allocations among the asset and sub-asset classes or, among other things, adding or removing asset and sub-asset classes or maintaining long-term strategic target allocations for longer or shorter periods of time. Consistent with this strategy, the Fund’s strategic target allocations shown in the glide path and table above may be different from the Fund’s actual strategic target allocations by +/- 5% for the equity, fixed income, money market/cash and cash equivalents and commodity asset and sub-asset classes. Additionally, as a result of short to intermediate term tactical allocations, the Fund may deviate from the strategic target allocations at any given time by up to +/- 15% for equity and fixed income, +/- 20% for money market/cash and cash equivalents and +/- 5% for commodity asset and sub-asset classes. The Adviser will review its tactical decisions on a periodic basis and may make modifications in its discretion.

As a result of the Adviser’s ability to make these modifications, the Fund’s actual allocations may differ from what is shown in the glide path and table above. Updated information concerning the Fund’s strategic target allocations and actual allocations to underlying funds and investments is available in the Fund’s shareholder reports and on the Fund’s website from time to time.

The Fund is a “to” target date fund. This means that the Fund intends to reach its most conservative strategic target allocations by the end of the year of the target retirement date. When the strategic target allocations of the Fund are substantially the same as those of the JPMorgan SmartRetirement Income Fund, the Fund may be merged into the JPMorgan SmartRetirement Income Fund at the discretion of the Fund’s Board of Trustees.

In addition to investing in mutual funds within the same group of investment companies, the Fund may invest in ETFs within the same group of investment companies (together with mutual funds within the same group of investment companies, J.P. Morgan Funds) and may, for the limited purposes described below, also invest in market cap weighted index ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs) (collectively with the J.P. Morgan Funds, the underlying funds). The Fund may also invest directly in securities and derivatives. Derivatives are instruments that have a value based on another instrument, exchange rate or index such as futures. The Fund may use futures contracts to gain exposure to, or to overweight or underweight its investments among, various sectors or markets. The Fund may also use exchange traded futures for cash management and to gain market exposure pending investment in underlying funds.

The Adviser will select and substitute underlying funds. In selecting underlying funds, the Adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For actively-managed underlying funds, the Adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the Adviser expects to use a J.P. Morgan ETF unless the Adviser determines the investment is not available. To the extent the Adviser determines that an investment in a J.P. Morgan passive ETF is not available, only then will the Adviser consider an unaffiliated underlying fund.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular instruments or markets are not met. The Fund is exposed to the risks summarized below through both its investments in underlying funds and its direct investments.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investment Risk. The Fund is not a complete retirement program and there is no guarantee that the Fund will provide sufficient retirement income to an investor. Meeting your retirement goals is dependent upon many factors including the amount you save and the period over which you do so. You should consider your expected retirement date, individual retirement needs (i.e., how much money you expect to need), other expected income after retirement, inflation, other assets, and risk tolerance in choosing whether to invest in the Fund. Your risk tolerance may change over time and the Adviser may change the Fund’s strategic target allocation model. It is important that you re-evaluate your investment in the Fund periodically.

Investments in Mutual Funds Risk. The Fund invests in other underlying funds that are mutual funds as a primary strategy, so the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s Adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the Adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated ETFs creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds.

Tactical Allocation Risk. The Adviser has discretion to make short to intermediate term tactical allocations that increase or decrease the exposure to asset classes and investments shown in the glide path. The Fund’s tactical allocation strategy may not be successful in adding value, may increase losses to the Fund and/or cause the Fund to have a risk profile different than that portrayed in the glide path from time to time.

Equity Securities Risk. Investments in equity securities (such as stocks) are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s or the underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of such securities goes down, the Fund’s investment decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in some of the underlying funds may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” an underlying fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Income Securities Risk. Investments in income securities are subject to interest rate risk and credit risk. The Fund’s exposure to bonds and other debt securities will change in value based on changes in interest rates. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Income securities are also subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Some of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of principal and interest. This would result in losses to an underlying fund. Securities issued by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund or underlying fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

High Yield Securities and Loan Risk. Certain underlying funds invest in junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid.

No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. Certain Loans may take more than seven days to settle. The inability to dispose of the underlying fund’s securities and other investments in a timely fashion could result in losses to the Fund and underlying fund. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for certain underlying funds than for underlying funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, an underlying fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these securities, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Real Estate Securities Risk. The Fund may be exposed through its direct investments or investments in underlying funds to real estate securities, including real estate investment trusts (REITs). These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with management skill and creditworthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITs.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other securities, especially over the short term.

Derivatives Risk. The underlying funds and the Fund may use derivatives, including futures contracts and exchange traded futures. Derivatives may be riskier than other investments and may increase the volatility of the Fund and the underlying funds. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s or an underlying fund’s original investment. Certain derivatives expose the Fund and the underlying funds to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligation (including credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or the underlying fund do not have a claim on the reference assets and are subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund and the underlying funds may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund and underlying funds to risks of mispricing or improper valuation.

Commodity Risk. Exposure to commodities, commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Inflation Managed Strategy Risk. The Fund may invest in underlying funds that utilize derivatives and debt securities to mimic a portfolio of inflation-protected bonds. There is no guarantee that this strategy will be effective. In addition, the Fund may be exposed to inflation-protected securities. Unlike conventional bonds, the principal and interest payments on inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) are adjusted periodically to a specified rate of inflation (i.e., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). Exposure to TIPS and other inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of a TIPS tends to decline when real interest rates increase.

Securities and Financial Instruments Risk. The Fund’s direct investments in securities and financial instruments are subject to additional risks specific to their structure, sector or market (e.g., futures and swaps on foreign securities are subject to foreign investment, emerging market and derivative risks; debt securities are subject to credit risk).

Industry and Sector Focus Risk. At times the underlying funds and the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds and the Fund increase the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[1] "Remainder of Other Expenses" and "Acquired Fund (Underlying Fund) Fees and Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund (Underlying Fund) Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.39% of the average daily net assets of the Class T Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/19, at which time the adviser and/or its affiliates will determine whether to renew or revise them. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

A, C, I Shares | JPMorgan Access Balanced Fund

<b>JPMorgan Access Balanced Fund <br/>Class/Ticker: A/JXBAX; C/JXBCX; I/JXBSX</b>

<b>What is the goal of the Fund?</b>

The Fund seeks total return.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $100,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “Investing with J.P. Morgan Funds — SALES CHARGES AND FINANCIAL INTERMEDIARY COMPENSATION” on page 46 and in “Financial Intermediary-Specific Sales Charge Waivers” in Appendix A of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information. You may be required to pay a commission to your Financial Intermediary for purchases of Class I Shares. Such commissions are not reflected in the tables or the example below.

<b>SHAREHOLDER FEES (Fees paid directly from your investment)</b>

Shareholder Fees - A, C, I Shares - JPMorgan Access Balanced Fund	Class A		Class C	Class I
Maximum Sales Charge (Load) Imposed on Purchases as a % of the Offering Price	4.50%		none	none
Maximum Deferred Sales Charge (Load) as a % of Original Cost of the Shares	none	[1]	1.00%	none

“Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES <br/>(Expenses that you pay each year as a percentage of the value <br/>of your investment)</b>

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example - A, C, I Shares - JPMorgan Access Balanced Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	584	942	1,323	2,390
CLASS C SHARES	288	659	1,156	2,526
CLASS I SHARES	112	428	768	1,726

<b>IF YOU DO NOT SELL YOUR SHARES, YOUR COST <br/>WOULD BE:</b>

Expense Example, No Redemption - A, C, I Shares - JPMorgan Access Balanced Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	584	942	1,323	2,390
CLASS C SHARES	188	659	1,156	2,526
CLASS I SHARES	112	428	768	1,726

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 30%–75% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 25%–60% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–30% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Balanced Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance</b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Access Balanced Composite Benchmark, a customized benchmark, the Bloomberg Barclays Global Aggregate Index - Hedged USD, a broad-based securities market index, the MSCI World Index (net of foreign withholding taxes), a broad-based securities market index, and the S&P 500 Index, a broad-based securities market index. Since January 1, 2018, the Access Balanced Composite Benchmark is a composite benchmark comprised of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of the MSCI World Index (net of foreign withholding taxes) (55%), Bloomberg Barclays Global Aggregate Index Hedged (40%), and HFRX Global Hedge Fund Index (5%). From July 1, 2016 until December 31, 2017, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (55%), Bloomberg Barclays Global Aggregate Index (35%), Bloomberg Barclays T-Bill 1-3 Month (5%), and HFRX Global Hedge Fund Index (5%). From April 1, 2013 until June 30, 2016, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (50%), Bloomberg Barclays U.S. Aggregate Index (35%), Citigroup 3-Month Treasury Bill Index (5%), Bloomberg Commodity Index (5%) and HFRX Global Hedge Fund Index (5%). From July 1, 2011 until April 1, 2013, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (50%), Bloomberg Barclays U.S. Aggregate Index (35%) and Citigroup 3-Month Treasury Bill Index (15%). From the inception date of September 30, 2009 to July 1, 2011, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (55%), Bloomberg Barclays Capital U.S. Aggregate Index (35%) and Citigroup 3-Month Treasury Bill Index (10%). The performance of Class C Shares is based on the performance of Class A Shares prior to their inception. The actual return of the Class C Shares would have been lower than shown because the Class C Shares have higher expenses than Class A Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganaccessfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

After-tax returns are shown only for the Class A Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases, the “Return After Taxes on Distributions and Sale of Fund Shares” may exceed the “Return Before Taxes” due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

[2] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.25% for Class A, Class C and Class I Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 30%–75% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 25%–60% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–30% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Balanced Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

<b>The Fund’s Past Performance</b>

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Access Balanced Composite Benchmark, a customized benchmark, the Bloomberg Barclays Global Aggregate Index - Hedged USD, a broad-based securities market index, the MSCI World Index (net of foreign withholding taxes), a broad-based securities market index, and the S&P 500 Index, a broad-based securities market index. Since January 1, 2018, the Access Balanced Composite Benchmark is a composite benchmark comprised of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of the MSCI World Index (net of foreign withholding taxes) (55%), Bloomberg Barclays Global Aggregate Index Hedged (40%), and HFRX Global Hedge Fund Index (5%). From July 1, 2016 until December 31, 2017, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (55%), Bloomberg Barclays Global Aggregate Index (35%), Bloomberg Barclays T-Bill 1-3 Month (5%), and HFRX Global Hedge Fund Index (5%). From April 1, 2013 until June 30, 2016, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (50%), Bloomberg Barclays U.S. Aggregate Index (35%), Citigroup 3-Month Treasury Bill Index (5%), Bloomberg Commodity Index (5%) and HFRX Global Hedge Fund Index (5%). From July 1, 2011 until April 1, 2013, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (50%), Bloomberg Barclays U.S. Aggregate Index (35%) and Citigroup 3-Month Treasury Bill Index (15%). From the inception date of September 30, 2009 to July 1, 2011, the Access Balanced Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (55%), Bloomberg Barclays Capital U.S. Aggregate Index (35%) and Citigroup 3-Month Treasury Bill Index (10%). The performance of Class C Shares is based on the performance of Class A Shares prior to their inception. The actual return of the Class C Shares would have been lower than shown because the Class C Shares have higher expenses than Class A Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganaccessfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

[2] J.P. Morgan Investment Management Inc. and J.P. Morgan Private Investments, Inc. have contractually agreed to waive the investment advisory fee for the Fund by 0.30%. This contract is in effect through 10/31/19.

[3] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.25% for Class A, Class C and Class I Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[4] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Balanced Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.

<b>What is the goal of the Fund?</b>

The Fund seeks total return.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 30%–75% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 25%–60% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–30% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Balanced Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases, the “Return After Taxes on Distributions and Sale of Fund Shares” may exceed the “Return Before Taxes” due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

[1] J.P. Morgan Investment Management Inc. and J.P. Morgan Private Investments, Inc. have contractually agreed to waive the investment advisory fee for the Fund by 0.30%. This contract is in effect through 10/31/19.

[2] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.10% for Class L Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Balanced Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 30%–75% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 25%–60% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–30% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Balanced Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] J.P. Morgan Investment Management Inc. and J.P. Morgan Private Investments, Inc. have contractually agreed to waive the investment advisory fee for the Fund by 0.30%. This contract is in effect through 10/31/19.

[2] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.10% for Class L Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Balanced Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 40%–90% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 5%–45% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–35% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Growth Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance</b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Access Growth Composite Benchmark, a customized benchmark, the MSCI World Index (net of foreign withholding taxes) a broad-based securities market index, the Bloomberg Barclays Global Aggregate Index – Hedged USD, a broad-based securities market index, and the S&P 500 Index, a broad-based securities market index. Since January 1, 2018, the Access Growth Composite Benchmark is a composite benchmark comprised of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Global Aggregate Index Hedged (20%), and HFRX Global Hedge Fund Index (5%). From July 1, 2016 until December 31, 2017, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Global Aggregate Index (15%), Bloomberg Barclays T-Bill 1-3 Month (5%), and HFRX Global Hedge Fund Index (5%). From April 1, 2013 until June 30, 2016, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (70%), Bloomberg Barclays U.S. Aggregate Index (15%), Citigroup 3-Month Treasury Bill Index (5%), Bloomberg Commodity Index (5%) and HFRX Global Hedge Fund Index (5%). From July 1, 2011 until April 1, 2013, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (70%), Bloomberg Barclays U.S. Aggregate Index (20%) and Citigroup 3-Month Treasury Bill Index (10%). From the inception date of September 30, 2009 to July 1, 2011, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Capital U.S. Aggregate Index (15%) and Citigroup 3-Month Treasury Bill Index (10%). The performance of Class C Shares is based on the performance of Class A Shares prior to their inception. The actual return of the Class C Shares would have been lower than shown because the Class C Shares have higher expenses than Class A Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganaccessfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

After-tax returns are shown only for the Class A Shares and after-tax returns for the other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases, the “Return After Taxes on Distributions and Sale of Fund Shares” may exceed the “Return Before Taxes” due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.25% for Class A, Class C and Class I Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Growth Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Strategy [Heading]

<b>What are the Fund’s main investment strategies? </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 40%–90% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 5%–45% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–35% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Growth Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

Risk [Heading]

rr_RiskHeading

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

<b>The Fund’s Past Performance</b>

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Access Growth Composite Benchmark, a customized benchmark, the MSCI World Index (net of foreign withholding taxes) a broad-based securities market index, the Bloomberg Barclays Global Aggregate Index – Hedged USD, a broad-based securities market index, and the S&P 500 Index, a broad-based securities market index. Since January 1, 2018, the Access Growth Composite Benchmark is a composite benchmark comprised of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Global Aggregate Index Hedged (20%), and HFRX Global Hedge Fund Index (5%). From July 1, 2016 until December 31, 2017, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Global Aggregate Index (15%), Bloomberg Barclays T-Bill 1-3 Month (5%), and HFRX Global Hedge Fund Index (5%). From April 1, 2013 until June 30, 2016, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (70%), Bloomberg Barclays U.S. Aggregate Index (15%), Citigroup 3-Month Treasury Bill Index (5%), Bloomberg Commodity Index (5%) and HFRX Global Hedge Fund Index (5%). From July 1, 2011 until April 1, 2013, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (70%), Bloomberg Barclays U.S. Aggregate Index (20%) and Citigroup 3-Month Treasury Bill Index (10%). From the inception date of September 30, 2009 to July 1, 2011, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Capital U.S. Aggregate Index (15%) and Citigroup 3-Month Treasury Bill Index (10%). The performance of Class C Shares is based on the performance of Class A Shares prior to their inception. The actual return of the Class C Shares would have been lower than shown because the Class C Shares have higher expenses than Class A Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

[2] J.P. Morgan Investment Management Inc. and J.P. Morgan Private Investments, Inc. have contractually agreed to waive the investment advisory fee for the Fund by 0.30%. This contract is in effect through 10/31/19.

[3] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.25% for Class A, Class C and Class I Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[4] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Growth Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.

<b>JPMorgan Access Growth Fund <br/>Class/Ticker: L/JXGIX</b>

<b>What is the goal of the Fund?</b>

The Fund seeks capital appreciation.

<b>Fees and Expenses of the Fund </b>

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

<b>ANNUAL FUND OPERATING EXPENSES</b><br/><b>(Expenses that you pay each year as a percentage of the value<br/>of your investment)</b>

Annual Fund Operating Expenses	L Shares JPMorgan Access Growth Fund Class L
Management Fees	0.75%	[1],[2]
Distribution (Rule 12b-1) Fees	none
Other Expenses	0.26%
Service Fees	0.10%	[2]
Remainder of Other Expenses	0.16%
Acquired Fund (Underlying Fund) Fees and Expenses	0.30%

<b>Example </b>

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example	1 Year	3 Years	5 Years	10 Years
L Shares | JPMorgan Access Growth Fund | CLASS L SHARES | USD ($)	98	381	685	1,548

<b>WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:</b>

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
L Shares | JPMorgan Access Growth Fund | CLASS L SHARES | USD ($)	98	381	685	1,548

<b>Portfolio Turnover </b>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

<b>What are the Fund’s main investment strategies? </b>

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 40%–90% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 5%–45% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–35% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Growth Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

<b>The Fund’s Main Investment Risks </b>

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

<b>The Fund’s Past Performance</b>

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class L Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Access Growth Composite Benchmark, a customized benchmark, the MSCI World Index (net of foreign withholding taxes), a broad-based securities market index, the Bloomberg Barclays Global Aggregate Index – Hedged USD, a broad-based securities market index, and the S&P 500 Index, a broad-based securities market index. Since January 1, 2018, the Access Growth Composite Benchmark is a composite benchmark comprised of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Global Aggregate Index Hedged (20%), and HFRX Global Hedge Fund Index (5%). From July 1, 2016 until December 31, 2017, the Access Growth Composite Benchmark was a composite benchmark comprised of the MSCI World Index (net of foreign withholding taxes) (75%), Bloomberg Barclays Global Aggregate Index (15%), Bloomberg Barclays T-Bill 1-3 Month (5%), and HFRX Global Hedge Fund Index (5%).

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases, the “Return After Taxes on Distributions and Sale of Fund Shares” may exceed the “Return Before Taxes” due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

[1] J.P. Morgan Investment Management Inc. and J.P. Morgan Private Investments, Inc. have contractually agreed to waive the investment advisory fee for the Fund by 0.30%. This contract is in effect through 10/31/19.

[2] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.10% for Class L Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Growth Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a combination of domestic and international equity, fixed income, and alternative assets, as described below. The Fund invests in mutual funds and exchange-traded funds (ETFs) in the same group of investment companies (i.e., J.P. Morgan Funds). The Fund also invests in open-end and closed-end investment companies (which may or may not be registered under the Investment Company Act of 1940, as amended) and ETFs that are managed by unaffiliated investment advisers (collectively, unaffiliated funds) and directly in individual securities. In addition, to the extent permitted by applicable law or the exemptive relief obtained from the Securities and Exchange Commission (SEC), the Fund invests directly in other financial instruments, including derivatives, such as futures, swaps and structured investments, to gain exposure to, or to overweight or underweight allocations among, various sectors or markets.

The Fund’s adviser is J.P. Morgan Investment Management Inc. (JPMIM or the Adviser) and it sets the Fund’s overall investment strategies. The Fund is managed by J.P. Morgan Private Investments Inc. (JPMPI). JPMPI utilizes an allocation process (Strategic Asset Allocations) to invest the Fund’s assets across the various asset classes and with various sub-advisers. JPMPI and JPMIM use rigorous criteria to select sub-advisers and underlying fund managers to manage certain portions of the Fund’s assets. In choosing whether to buy or sell an investment and to set their allocations, JPMPI considers the following factors: (1) market trends, (2) JPMPI’s outlook for a market capitalization or investment style category, and (3) an underlying fund manager’s performance in various market conditions. JPMPI will also consider the advantages and disadvantages to the Fund of using actively versus passively managed investment vehicles. By combining the strengths of different sub-advisers and underlying fund managers, the Fund seeks to benefit from a variety of investment selection processes and methodologies to achieve its investment objective.

The descriptions below include both the range that the Fund may invest within a particular asset class and the various investments that the Fund may use to gain exposure to such asset class. JPMPI frequently monitors and may make tactical changes to the Strategic Asset Allocations, including shifts among the various asset classes and allocations to the other sub-advisers and underlying fund managers.

U.S. and International Equity: The allocation range will typically be 40%–90% of the Fund’s total assets. The Fund’s equity-related investments consist of J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class are: common stock, preferred stock, structured investments, convertible securities, depositary receipts and warrants to buy common stocks. The Fund invests in foreign and emerging market securities.

U.S. and International Fixed Income: The allocation range will typically be 5%–45% of the Fund’s total assets. The Fund’s fixed income investments include J.P. Morgan Funds, unaffiliated funds and individual securities. Whether investing through an investment company or directly in securities, the investments in this asset class include: U.S. government securities (including agencies and instrumentalities), municipal bonds (including housing authority obligations), domestic and foreign corporate bonds, high yield securities (junk bonds), loan participations and assignments, debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, mortgage-backed and asset-backed securities, inflation-indexed bonds and Treasury Inflation Protected Securities (TIPS).

Alternative: The allocation range will typically be 0%–35% of the Fund’s total assets. The Fund’s alternative-related investments include J.P. Morgan Funds and unaffiliated funds. Whether investing through a mutual fund or directly in securities, the investments in this asset class give the Fund exposure to: market neutral strategies, absolute return strategies, directional strategies, real estate (including REITs), private equity, mezzanine debt and commodities.

The Fund will gain exposure to commodity markets primarily by investing in the Access Growth Fund CS Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The allocation range will typically be 0%–10% of the Fund’s total assets. The Subsidiary is advised by JPMIM and sub-advised by JPMPI. The Subsidiary (unlike the Fund) may invest without limitation in commodity-linked structured notes and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund. The Subsidiary may use derivatives to obtain long exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management.

The Fund and the Subsidiary may invest in ETFs, including both JPMorgan ETFs and unaffiliated funds, in order to gain exposure to particular asset classes. An ETF is a registered investment company, depositary receipt or other pooled investment vehicle that typically seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions or industries.

Ordinarily, the Fund’s investment in a single unaffiliated ETF is limited to 5% of its total assets and in all unaffiliated ETFs to 10% of its total assets. The SEC has issued exemptive orders to many ETFs that allow any fund investing in such ETFs to disregard these 5% and 10% limitations. The Fund intends to invest in unaffiliated ETFs that have received such exemptive orders and it may invest any amount of its total assets in a single ETF or in multiple ETFs.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund uses structured notes as tools in the management of portfolio assets. In particular, the Fund uses structured notes for risk management and to increase the Fund’s income or gain. To the extent that the Fund invests in underlying funds, such underlying funds may also use derivatives.

Risk [Heading]

rr_RiskHeading

<b>The Fund’s Main Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Investments in Mutual Funds and ETFs Risk. The Fund’s investments are concentrated in J.P. Morgan Funds and unaffiliated funds, so the Fund’s investment performance is directly related to the performance of the underlying funds. Shareholders will indirectly bear the expenses incurred by the underlying funds. In addition, the Adviser’s authority to allocate investments among J.P. Morgan Funds and unaffiliated funds creates conflicts of interest. For example, investing in J.P. Morgan Funds could cause the Fund to incur higher fees and will cause the Adviser and/or its affiliates to receive greater compensation, increase assets under management or support particular investment strategies or J.P. Morgan Funds. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Foreign Securities and Emerging Markets Risk. The Fund and certain of the underlying funds that invest in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Country and Region Risk. Some of the underlying funds concentrate their investments in securities of a single country or region (e.g., China Region or Latin America). Because these underlying funds concentrate their investments in a single country or region, their performance may be more volatile than that of a fund that can invest globally.

Industry and Sector Focus Risk. At times the underlying funds or the Fund may increase the relative emphasis of their investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the underlying funds or the Fund increase the relative emphasis of their investments in a particular industry or sector, their shares’ values may fluctuate in response to events affecting that industry or sector.

Currency Risk. The Fund and certain of the underlying funds are subject to risks associated with foreign currency. Certain underlying funds are not required to hedge their non-dollar investments back to the U.S. dollar for defensive purposes. As a result, changes in foreign currency exchange rates will affect the value of certain underlying funds’ securities and the price of the underlying funds’ shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund.

Equity Securities Risk. The Fund and certain of the underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. When the value of the stocks held by the Fund or an underlying fund goes down, the value of your investment in the Fund decreases in value.

Fixed Income Securities Risk. Some of the underlying funds invest in fixed income securities. These securities will increase or decrease in value based on changes in interest rates and are subject to the risk that an issuer or a counterparty will fail to make payments when due or default. If an issuer’s or a counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate making it difficult for the underlying fund to sell such investments. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. When the value of investments in the Fund or underlying fixed income funds goes down, the value of your investment in the Fund will be affected. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. Certain of the underlying funds may invest in instruments that are issued by companies which are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information.

Real Estate Securities Risk. Certain of the underlying funds may invest in real estate securities, including real estate investment trusts (REITs), which are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the underlying fund.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodity-related securities and derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The Fund and certain of the underlying funds may use derivatives in connection with their investment strategies. Derivatives, including futures, swaps and structured investments, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would have been if it had not used derivatives. Certain derivatives also expose the Fund and the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund or underlying funds do not have a claim on the reference assets and are subject to enhanced counterparty risk. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund and certain of the underlying funds may use derivatives for non-hedging purposes, which increases the Fund’s or the underlying funds’ potential for loss.

Structured Note Risk. The Fund, or certain of the underlying funds, invest in commodity, currency, equity and fixed income linked structured notes. Structured notes are typically privately negotiated transactions between two or more parties. The fees associated with a structured note may lead to increased tracking error. The Fund also bears the risk that the issuer of the structured note will default. The Fund bears the risk of loss of its principal investment and periodic payments expected to be received for the duration of its investment. In addition, a liquid market may not exist for the structured notes. The lack of a liquid market may make it difficult to sell the structured notes at an acceptable price or to accurately value them.

Index Investing Risk. Certain of the underlying funds, including ETFs, in which the Fund may invest are index funds. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Preferred Stock Risk. The Fund and certain underlying funds may invest in preferred stock. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Government Securities Risk. The Fund and certain of the underlying funds invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and could adversely affect the Fund.

Transactions Risk. The Fund or an underlying fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, for both the Fund and underlying funds, large purchases of a fund’s shares may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

[1] J.P. Morgan Investment Management Inc. and J.P. Morgan Private Investments, Inc. have contractually agreed to waive the investment advisory fee for the Fund by 0.30%. This contract is in effect through 10/31/19.

[2] The shares of the affiliated underlying funds in which the Fund invests a portion of its assets impose a separate investment advisory fee and a service fee. To avoid charging an investment advisory fee and a service fee at an effective rate above 0.45% for investment advisory services and 0.10% for Class L Shares for shareholder servicing on affiliated investments, the investment adviser and shareholder servicing agent have contractually agreed to waive a portion of the investment advisory and service fees charged by the underlying funds. This contract is in effect through 10/31/19. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

[3] The Fund’s adviser has contractually agreed to waive the advisory fee that it receives from the Fund in an amount equal to the advisory fee paid by Access Growth Fund CS Ltd., the Fund’s wholly-owned subsidiary, to its adviser. This waiver will continue in effect so long as the Fund invests in the subsidiary and may not be terminated without approval by the Fund’s Board of Trustees.
