Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Goldman Sachs N-11 Equity Fund (the “Fund”) seeks long-term capital appreciation.
Expense [Heading]	rr_ExpenseHeading	<b>Fees and Expenses of the Fund</b>
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The table does not take into account brokerage commissions that you may pay on your purchases and sales of Institutional Shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you invest at least $50,000 in Goldman Sachs Funds.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended October 31, 2018 was 11% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	11.00%

Expense Example [Heading]	rr_ExpenseExampleHeading	<b>Expense Example</b>
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	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 Class A, Class C, Institutional, Investor and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor and/or Class R6 Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the expense limitation arrangement for only the first year). The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Institutional Shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<b>Principal Strategies</b>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a portfolio of equity investments that are tied economically to the “N-11 countries,” as defined below, or in issuers that participate in the markets of the N-11 countries. The Investment Adviser considers an investment to be tied economically to the N-11 countries if the investment is included in an index representative of one or more N-11 countries, the investment’s returns are linked to the performance of such an index, or the investment is exposed to the economic risks and returns of one or more N-11 countries. The “N-11 countries” are countries that have been identified by the Goldman Sachs Global Economics, Commodities, and Strategy Research Team as the “Next Eleven” emerging countries after the BRICs (i.e., after Brazil, Russia, India and China) that share the potential to experience high economic growth and be important contributors to global gross domestic product (GDP) in the future. The N-11 countries are Bangladesh, Egypt, Indonesia, Iran, Mexico, Nigeria, Pakistan, Philippines, South Korea, Turkey and Vietnam. The Fund will not invest in issuers organized under the laws of Iran, or domiciled in Iran, or in certain other issuers as necessary to comply with U.S. economic sanctions against Iran. Only securities open to foreign ownership by U.S. investors are eligible for investment by the Fund, and in some instances the Fund may be subject to foreign ownership limitations in these countries. The Fund may not be invested in all of the N-11 countries at all times. Under normal circumstances, the Fund maintains investments that are tied economically to and/or issuers that participate in the markets of at least four of the N-11 countries, and will not invest more than 50% of its Net Assets in investments that are tied economically to and/or issuers that participate in the markets of any one country. The Fund expects to invest primarily in equity securities, including common or ordinary stocks, American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), preferred stock, convertible securities, investment companies (including other mutual funds or exchange-traded funds (“ETFs”)), and rights and warrants. The Fund also intends to invest in derivatives, including (but not limited to) equity swaps, equity index swaps, futures, participation notes, options and other derivatives and structured securities, which are used primarily to gain broad access to markets and/or individual securities that may be difficult to access via direct investment in equity securities. The Fund’s investments are selected using a strong valuation discipline based on industry specific metrics, to purchase what the Investment Adviser believes are well positioned, cash-generating businesses run by shareholder-oriented management teams. From a valuation perspective, the Investment Adviser generally looks for companies where its proprietary estimate of their earnings, asset value or cash flow is meaningfully different from consensus; or where the Investment Adviser believes growth in intrinsic value is not reflected in the share price. Allocation of the Fund’s investments is determined by the Investment Adviser’s assessment of a company’s upside potential and downside risk, how attractive it appears relative to the Fund’s other holdings, and how the addition will impact the Fund’s sector and industry weightings. The largest weightings are given to companies the Investment Adviser believes have the most upside return potential relative to their contribution to overall portfolio risk. The Fund’s investments may include companies of all capitalization sizes. The Fund may invest in the aggregate up to 20% of its Net Assets in: (i) developed country investments and other emerging country investments; and (ii) fixed income investments, including non-investment grade fixed income securities. The Fund will not invest more than 25% of the value of its total assets in the securities of one or more issuers conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark index at the time of investment, the Fund may invest up to 35% of its assets in that industry. The Fund’s benchmark index is the Morgan Stanley Capital International (MSCI) Next 11 ex-Iran GDP Weighted Index (Net, USD, Unhedged).
Risk [Heading]	rr_RiskHeading	<b>Principal Risks of the Fund</b>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Banking Industry Risk.  An adverse development in the banking industry may affect the value of the Fund’s investments more than if the Fund were not invested to such a degree in the banking industry. Banks may be particularly susceptible to certain economic factors such as interest rate changes, adverse developments in the real estate market, fiscal, regulatory and monetary policy and general economic cycles. Foreign and Emerging Countries Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging countries. The Fund will invest heavily in issuers located in or that participate in the markets of Bangladesh, Egypt, Indonesia, Mexico, Nigeria, Pakistan, Philippines, South Korea, Turkey and Vietnam and therefore will be particularly exposed to the economies, industries, securities and currency markets of these countries, which may be adversely affected by protectionist trade policies, slow economic activity worldwide, political and social instability, environmental events and natural disasters, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the U.S. The N-11 countries currently generally have smaller economies or less developed capital markets than traditional emerging markets countries, and, as a result, the risks of investing in emerging market countries are magnified in these countries. Foreign Custody Risk.  The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often underdeveloped and may be considerably less well regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries. Industry Concentration Risk.  The Fund will not invest more than 25% of its total assets in the securities of one or more issuers conducting their principal business activities in the same industry or group of industries, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark index at the time of investment, the Fund may invest up to 35% of its assets in that industry. Concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries will subject the Fund to a greater risk of loss as a result of adverse economic, business, political, environmental or other developments than if its investments were diversified across different industries. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Liquidity Risk.  The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging market countries. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Sector Risk.  To the extent the Fund focuses its investments in one or more sectors (such as the financial services or telecommunications sectors), the Fund will be subject, to a greater extent than if its investments were diversified across different sectors, to the risks of volatile economic cycles and/or conditions or developments that may be particular to that sector, such as: adverse economic, business, political, environmental or other developments. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class R6 Shares have been restated to reflect expenses expected to be incurred during the current fiscal year.

[4] The “Total Annual Fund Operating Expenses” do not correlate to the ratios of net and total expenses to average net assets provided in the Financial Highlights, which reflect the operating expenses of the Fund and do not include “Acquired Fund Fees and Expenses.”

[5] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.164% of the Fund’s average daily net assets through at least February 28, 2020, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[6] After Expense Limitation

[7] Class R6 Shares commenced operations on February 28, 2018. Performance of the Class R6 Shares is that of the Institutional Shares. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had similar returns (because these share classes represent interests in the same portfolio of securities) that differed only to the extent that Class R6 Shares and Institutional Shares have different expenses.
