to the Prospectus and Summary Prospectus of the following fund:

Fund	Prospectus Dated
Columbia Funds Series Trust II
Active Portfolios^®Multi-Manager Value Fund	10/1/2015

Effective on or about June 27, 2016 (the Effective Date), the first, second and third paragraphs under the subsection "Principal Investment Strategies” in the "Summary of the Fund" section of the Prospectus are hereby superseded and replaced with the following:

The Fund’s assets primarily are invested in equity securities. These equity securities generally include common stocks, but may also include preferred stocks and convertible securities. The Fund may invest in companies that have market capitalizations of any size.

The Fund may invest up to 20% of its net assets in debt instruments, including those that, at the time of purchase, are rated below investment grade or are unrated but determined to be of comparable quality (commonly referred to as “high yield” investments or “junk” bonds).

The Fund may invest up to 25% of its net assets in foreign investments. The Fund may invest in foreign securities directly or indirectly through depositary receipts.

The Fund may invest in derivatives, including futures contracts (including equity index futures) to gain market exposure on the Fund’s uninvested cash pending investment in securities or to maintain liquidity to pay redemptions, to hedge existing positions, and to increase market exposure and investment flexibility, including using the derivative as a substitute for the purchase or sale of an underlying security(ies) or basket of securities.

The Fund may also hold/invest in cash, money market instruments (which may include investments in one or more affiliated or unaffiliated money market funds or similar vehicles) or other high-quality, short-term investments, including for the purpose of covering its obligations with respect to, or that may result from, the Fund’s investments in derivatives.

The Fund may also invest in exchange-traded funds (ETFs).

On the Effective Date, the following is added as the last paragraph under the subsection "Principal Investment Strategies” in the "Summary of the Fund" section of the Prospectus:

The Investment Manager combines fundamental and quantitative analysis with risk management in identifying investment opportunities and constructing the Fund’s portfolio.

On the Effective Date, the information under the subsection "Principal Risks" in the "Summary of the Fund" section of the Prospectus is hereby revised to remove Derivatives Risk/Equity-Linked Notes Risk and Derivatives Risk/Structured Investments Risk. Additionally, Convertible Securities Risk, Credit Risk, Depositary Receipts Risk, Exchange-Traded Fund (ETF) Risk, High-Yield Investments Risk, Interest Rate Risk, Money Market Fund Investment Risk, Preferred Stock Risk and Quantitative Model Risk are added as follows:

Convertible Securities Risk. Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate risk and credit risk. Convertible securities also react to changes in the value of the common stock into which they convert, and are thus subject to market risk. The Fund may also be forced to convert a convertible security at an inopportune time, which may decrease the Fund’s return.

Credit Risk. Credit risk is the risk that the value of debt instruments may decline if the issuer thereof defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Rating agencies assign credit ratings to certain fixed-income securities to indicate their credit risk. Lower quality or unrated securities held by the Fund may present increased credit risk as compared to higher-rated securities. Non-investment grade fixed-income instruments (commonly called “high-yield” or “junk”) may be subject to greater price fluctuations and are more likely to experience a default than investment grade fixed-income instruments and therefore may expose the Fund to increased credit risk. If the Fund purchases unrated securities, or if the ratings of securities held by the Fund are lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual.

foreign securities, including those associated with investing in the particular country of an issuer, which may be related to the particular political, regulatory, economic, social and other conditions or events occurring in the country and fluctuations in its currency, as well as market risk tied to the underlying foreign company. In addition, ADR holders may have limited voting rights, may not have the same rights afforded typical company stockholders in the event of a corporate action such as an acquisition, merger or rights offering and may experience difficulty in receiving company stockholder communications.

Exchange-Traded Fund (ETF) Risk. ETFs are subject to, among other risks, tracking risk and passive and, in some cases, active investment risk. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses incurred through ownership of the ETF.

High-Yield Investments Risk. Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called “high-yield” or “junk” bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates (which are at historic lows) rise, the values of fixed-income instruments tend to fall, and if interest rates fall, the values of fixed-income instruments tend to rise. Changes in the value of a fixed-income instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of the Fund's shares. In general, the longer the maturity or duration of a fixed-income instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Similarly, a period of rising interest rates may negatively impact the Fund’s performance. Actions by governments and central banking authorities can result in increases in interest rates. Such actions may negatively affect the value of fixed-income instruments held by the Fund, resulting in a negative impact on the Fund's performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in fixed-income instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Money Market Fund Investment Risk. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Although certain types of money market funds seek to preserve the value of investments at $1.00 per share, it is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests, including affiliated money market funds. The Fund will also be exposed to the investment risks of the money market fund. To the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from its investments in derivatives. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds. In the event that a money market fund’s portfolio liquidity declines below a certain level, the money market fund’s board may impose a liquidity fee on redemptions of up to 2% or suspend redemptions for a period of time (i.e., impose a redemption gate). These measures may result in an investment loss or prohibit the Fund from redeeming shares when the Investment Manager would otherwise redeem shares.

Preferred Stock Risk. Preferred stock is a type of stock that generally pays dividends at a specified rate and that has preference over common stock in the payment of dividends and the liquidation of assets. Preferred stock does not ordinarily carry voting rights. The price of a preferred stock is generally determined by earnings, type of products or services, projected growth rates, experience of management, liquidity, and general market conditions of the markets on which the stock trades. The most significant risks associated with investments in preferred stock include issuer risk, market risk and interest rate risk (i.e., the risk of losses attributable to changes in interest rates).

Quantitative Model Risk. Investments selected using quantitative methods may perform differently from the market as a whole. There can be no assurance that these methodologies will enable the Fund to achieve its objective.

On the Effective Date, the caption "Columbia Management" and the information beneath it, under the subsection “Principal Investment Strategies” in the "More Information About the Fund" section of the Prospectus, are hereby superseded and replaced with the following:

Columbia Management

The Investment Manager combines fundamental and quantitative analysis with risk management in identifying investment opportunities and constructing the Fund’s portfolio.

In selecting investments, the Investment Manager considers, among other factors:

■	various measures of valuation, including price-to-cash flow, price-to-earnings, price-to-sales, and price-to-book value. The Investment Manager believes that companies with lower valuations are generally more likely to provide opportunities for capital appreciation;
■	potential indicators of stock price appreciation, such as anticipated earnings growth, company restructuring, changes in management, business model changes, new product opportunities, or anticipated improvements in macroeconomic factors;
■	the financial condition and management of a company, including its competitive position, the quality of its balance sheet and earnings, its future prospects, and the potential for growth and stock price appreciation;
■	overall economic and market conditions.

The Investment Manager may sell a security when the security’s price reaches a target set by the Investment Manager; if the Investment Manager believes that there is deterioration in the issuer’s financial circumstances or fundamental prospects; if other investments are more attractive; or for other reasons.

SUP116_05_002_(06/16)

Columbia Management is also responsible for managing cash flows into and out of the Fund resulting from the purchase and redemption of Fund shares. For this purpose, Columbia Management may invest in the instruments described above as well as in affiliated or unaffiliated money market funds.

On the Effective Date, the information under the subsection "Principal Risks" in the "More Information About the Fund" section of the Prospectus is hereby revised to remove Derivatives Risk/Equity-Linked Notes Risk and Derivatives Risk/Structured Investments Risk. Additionally, Convertible Securities Risk, Credit Risk, Depositary Receipts Risk, Exchange-Traded Fund (ETF) Risk, High-Yield Investments Risk, Interest Rate Risk, Money Market Fund Investment Risk, Preferred Stock Risk and Quantitative Model Risk are added as follows:

Convertible Securities Risk. Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate risk (the risk of losses attributable to changes in interest rates) and credit risk (the risk that the issuer of a debt instrument will default or otherwise become unable, or be perceived to be unable or unwilling, to honor a financial obligation, such as making payments to the Fund when due). Convertible securities also react to changes in the value of the common stock into which they convert, and are thus subject to market risk (the risk that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise). Because the value of a convertible security can be influenced by both interest rates and the common stock's market movements, a convertible security generally is not as sensitive to interest rates as a similar debt instrument, and generally will not vary in value in response to other factors to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would typically be paid before the company's common stockholders but after holders of any senior debt obligations of the company. The Fund may be forced to convert a convertible security before it otherwise would choose to do so, which may decrease the Fund's return.

Credit Risk. Credit risk is the risk that the value of debt instruments may decline if the issuer thereof defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Various factors could affect the actual or perceived willingness or ability of the issuer to make timely interest or principal payments, including changes in the financial condition of the issuer or in general economic conditions. Rating agencies assign credit ratings to certain fixed-income instruments to indicate their credit risk. Lower quality or unrated securities held by the Fund may present increased credit risk as compared to higher-rated securities. Non-investment grade fixed-income instruments (commonly called “high-yield” or “junk”) may be subject to greater price fluctuations and are more likely to experience a default than investment grade fixed-income instruments and therefore may expose the Fund to increased credit risk. If the Fund purchases unrated fixed-income securities, or if the ratings of such investments held by the Fund are lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual.

Depositary Receipts Risk. Depositary receipts are receipts issued by a bank or trust company reflecting ownership of underlying securities issued by foreign companies. Some foreign securities are traded in the form of American Depositary Receipts (ADRs). Depositary receipts involve risks similar to the risks associated with investments in foreign securities, including those associated with investing in the particular country of an issuer, which may be related to the particular political, regulatory, economic, social and other conditions or events occurring in the country and fluctuations in its currency, as well as market risk tied to the underlying foreign company. In addition, ADR holders may have limited voting rights, may not have the same rights afforded typical company stockholders in the event of a corporate action such as an acquisition, merger or rights offering and may experience difficulty in receiving company stockholder communications.

Exchange-Traded Fund (ETF) Risk. An ETF’s share price may not track its specified market index (if any) and may trade below its NAV. Certain ETFs use a “passive” investment strategy and do not take defensive positions in volatile or declining markets. Other ETFs in which the Fund may invest are actively managed ETFs (i.e., they do not track a particular benchmark), which indirectly subjects the Fund to active management risk. An active secondary market in ETF shares may not develop or be maintained and may be halted or interrupted due to actions by its listing exchange, unusual market conditions or other reasons. There can be no assurance that an ETF’s shares will continue to be listed on an active exchange. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses incurred through ownership of the ETF. There is a risk that ETFs in which the Fund invests may terminate due to extraordinary events. For example, any of the service providers to ETFs, such as the trustee or sponsor, may close or otherwise fail to perform their obligations to the ETF, and the ETF may not be able to find a substitute service provider. Also, certain ETFs may be dependent upon licenses to use various indexes as a basis for determining their compositions and/or otherwise to use certain trade names. If these licenses are terminated, the ETFs may also terminate. In addition, an ETF may terminate if its net assets fall below a certain amount.

SUP116_05_002_(06/16)

High-Yield Investments Risk. Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called “high-yield” or “junk” bonds) and unrated debt instruments of comparable quality tend to be more sensitive to credit risk than higher-rated debt instruments and may experience greater price fluctuations in response to perceived changes in the ability of the issuing entity or obligor to pay interest and principal when due than to changes in interest rates. These investments are generally more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. These debt instruments typically pay a premium – a higher interest rate or yield – because of the increased risk of loss, including default. High-yield debt instruments may require a greater degree of judgment to establish a price, may be difficult to sell at the time and price the Fund desires, may carry high transaction costs, and also are generally less liquid than higher-rated debt instruments. The ratings provided by third party rating agencies are based on analyses by these ratings agencies of the credit quality of the debt instruments and may not take into account every risk related to whether interest or principal will be timely repaid. In adverse economic and other circumstances, issuers of lower-rated debt instruments are more likely to have difficulty making principal and interest payments than issuers of higher-rated debt instruments.

Money Market Fund Investment Risk. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Although certain types of money market funds seek to preserve the value of investments at $1.00 per share, it is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests, including affiliated money market funds. To the extent these fees and expenses, along with the fees and expenses of any other funds in which the Fund may invest, are expected to equal or exceed 0.01% of the Fund’s average daily net assets, they will be reflected in the Annual Fund Operating Expenses set forth in the table under “Fees and Expenses of the Fund.” By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective, and the Fund, through its investment in the money market fund, may not achieve its investment objective. To the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from its investments in derivatives. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds. In the event that a money market fund’s portfolio liquidity declines below a certain level, the money market fund’s board may impose a liquidity fee on redemptions of up to 2% or suspend redemptions for a period of time (i.e., impose a redemption gate). These measures may result in an investment loss or prohibit the Fund from redeeming shares when the Investment Manager would otherwise redeem shares.

Quantitative Model Risk. The Fund may use quantitative methods to select investments. Securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns, among others. Any errors or imperfections in

SUP116_05_002_(06/16)

the Fund portfolio manager’s quantitative analyses or models, or in the data on which they are based, could adversely affect the portfolio manager’s effective use of such analyses or models, which in turn could adversely affect the Fund’s performance. It is not possible or practicable for a manager to factor all relevant, available data into quantitative model forecasts and/or trading decisions. Quantitative managers will use their discretion to determine what data to gather with respect to an investment strategy and what data the models will take into account to produce forecasts that may have an impact on ultimate trading decisions. Shareholders should be aware that there is no guarantee that a quantitative manager will use any specific data or type of data in making trading decisions on behalf of the Fund, nor is there any guarantee that the data actually utilized in generating forecasts or making trading decisions on behalf of the Fund will be the most accurate data available or free from errors. There can be no assurance that these methodologies will enable the Fund to achieve its objective.
