to the Prospectus of the following fund:

Fund	Prospectus Dated
Columbia Funds Series Trust
Columbia Large Cap Core Fund	7/1/2013

Effective December 11, 2013 (the Effective Date), the Fund’s name will change to Columbia Select Large Cap Equity Fund. Accordingly, effective on such date, all references in the Prospectus to Columbia Large Cap Core Fund are deleted and replaced with Columbia Select Large Cap Equity Fund. In addition, the following changes are hereby made to the Fund’s prospectus on the Effective Date:

On the Effective Date, the information under the caption “Principal Investment Strategies” in the “Summary of the Fund” section is hereby superseded and replaced with the following:

Under normal circumstances, the Fund invests at least 80% of its net assets (including the amount of any borrowings for investment purposes) in equity securities of companies that have market capitalizations, at the time of purchase, in the range of companies in the Standard & Poor’s (S&P) 500 Index (the Index). The market capitalization range of the companies included within the Index was $2.7 billion to $433.1 billion as of September 30, 2013.

The Fund may invest up to 20% of its total assets in foreign securities. The Fund normally invests in common stocks, preferred stocks and convertible securities like warrants and rights and may invest in exchange-traded funds. The Fund may from time to time emphasize one or more economic sectors in selecting its investments, including the technology sector. Generally, the Fund anticipates holding between between 45 and 65 securities in its portfolio; however, the Fund may hold, at any time, more or less securities than noted in this range.

The Fund may invest in derivatives, including options and other derivative instruments. The Fund may invest in derivatives for both hedging and non-hedging purposes, including, for example, to seek to enhance returns or as a substitute for a position in an underlying asset.

On the Effective Date, the information under the caption "Principal Risks" in the "Summary of the Fund" section is hereby modified by adding the following disclosure to the existing list of risks:

Focused Portfolio Risk. Because the Fund may invest in a limited number of companies, the Fund as a whole is subject to greater risk of loss if any of those securities decline in price.

The rest of the section remains the same.

On the Effective Date, the information under the caption “Principal Investment Strategies” in the “More Information About the Fund” section is hereby superseded and replaced with the following:

Under normal circumstances, the Fund invests at least 80% of its net assets (including the amount of any borrowings for investment purposes) in equity securities of companies that have market capitalizations, at the time of purchase, in the range of companies in the Standard & Poor’s (S&P) 500 Index (the Index). The market capitalization range of the companies included within the Index was $2.7 billion to $433.1 billion as of September 30, 2013. Over time, the capitalizations of the companies in the Index will change. As they do, the size of the companies in which the Fund invests may change. As long as an investment continues to meet the Fund’s other investment criteria, the Fund may choose to continue to hold a stock even if the company’s market capitalization grows beyond the largest market capitalization of a company within the Index or falls below the market capitalization of the smallest company within the Index.

The Fund may invest up to 20% of its total assets in foreign securities. The Fund normally invests in common stocks, preferred stocks and convertible securities like warrants and rights and may invest in exchange-traded funds. The Fund may from time to time emphasize one or more economic sectors in selecting its investments, including the technology sector. Generally, the Fund anticipates holding between between 45 and 65 securities in its portfolio; however, the Fund may hold, at any time, more or less securities than noted in this range.

The Fund may invest in derivatives, including options and other derivative instruments. The Fund may invest in derivatives for both hedging and non-hedging purposes, including, for example, to seek to enhance returns or as a substitute for a position in an underlying asset.

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

In selecting investments, Columbia Management Investment Advisers, LLC (the Investment Manager) considers, among other factors:

■ overall economic and market conditions; and

SUP172_02_001_(11/13)

■ 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.

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, or that other investments are more attractive; or for other reasons.

The Fund’s investment policy with respect to 80% of its net assets may be changed by the Board of Trustees without shareholder approval as long as shareholders are given 60 days advance written notice of the change.

On the Effective Date, the section entitled "Principal Risks" in the "More Information About the Fund" section is hereby modified by adding the following disclosure to the existing list of risks:

Focused Portfolio Risk. The Fund, because it may invest in a limited number of companies, may have more volatility in its net asset value and is considered to have more risk than a fund that invests in a greater number of companies because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value. To the extent the Fund invests its assets in fewer securities, the Fund is subject to greater risk of loss if any of those securities decline in price.

The rest of the section remains the same.

Shareholders should retain this Supplement for future reference.
