the DREYFUS Socially responsible growth FUND, inc.

Supplement to Current Statement of Additional Information

In connection with a recommendation by The Dreyfus Corporation ("Dreyfus"), the fund's investment adviser, to change the fund's investment strategy to focus on sustainable and environmental, social and governance ("ESG") investing, the fund's board has approved, subject to shareholder approval, (1) changes to the fund's investment strategy, including removing the current fundamental social investment policy and related fundamental social considerations, and changes to the fund's fundamental investment objective, (2) the engagement of Newton Investment Management (North America) Limited ("Newton"), an affiliate of Dreyfus, as sub-adviser for the fund and (3) a "manager of managers" arrangement for the fund, each as described in the supplement to the fund's prospectus dated as of December 23, 2016 (the "Prospectus Supplement").  The Prospectus Supplement supersedes and replaces any contrary information in the SAI.  Shareholders of record as of the close of business on January 4, 2017 will be asked to vote at a special meeting of shareholders, to be held on March 9, 2017.  If approved by fund shareholders, these and other proposed changes described below will become effective on or about May 1, 2017 (the "Effective Date").  To be consistent with the proposed change to the fund's investment strategy, as of the Effective Date, the fund's name will be changed to "The Dreyfus Sustainable U.S. Equity Portfolio, Inc."  References to The Dreyfus Socially Responsible Growth Fund, Inc. throughout this SAI will be replaced with The Dreyfus Sustainable U.S. Equity Portfolio, Inc.

In addition to the proposed changes described in the Prospectus Supplement, the fund's board has approved, subject to shareholder approval, changing or removing certain of the fund's fundamental investment restrictions to provide the fund with additional investment flexibility, to clarify and/or expand the fund's ability to enter into certain types of transactions and/or to better align the relevant fundamental investment restrictions with those of other funds in the Dreyfus Family of Funds.  These restrictions pertain to investing in commodities, real estate, oil and gas, and certain derivative instruments; selling securities short; issuer diversification; industry concentration; margin; underwriting the securities of other issuers; investing for control; investing in companies with limited operations; investing in securities where affiliated persons are involved; and investing in warrants.  The changes to, or removal of, these fundamental investment restrictions are not required to enable the fund to change its investment strategy and Newton to fully implement its investment approach for the fund.  If approved by shareholders, these proposed changes also will take effect on the Effective Date.
