Re: FS Investment Corporation III

File No. 814-01047

Dear Ms. Hahn:

On behalf of FS Investment Corporation III (the “Company”), set forth below are the Company’s responses to the oral comments provided by the staff of the Division of Investment Management (the “Staff”) of the U.S. Securities and Exchange Commission (the “Commission”) in a telephone conversation on December 20, 2017 regarding the Company’s Preliminary Proxy Statement on Schedule 14A (File No. 814-01047) (the “Proxy Statement”). For your convenience, a summary of the Staff’s comments is presented in bold, italicized text below, and is followed by the Company’s responses, which include references to the changes the Company has made in the Company’s Definitive Proxy Statement on Schedule 14A filed with the Commission on the date hereof (the “Definitive Proxy Statement”) in response to such comments. Unless otherwise indicated, all page references are to page numbers in the Proxy Statement. Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Proxy Statement.

General Comments

1.    In the Letter to Stockholders and the Notice of Special Meeting of Stockholders and throughout the Proxy Statement, please clarify (i) that the Investment Co-Advisory Agreements are ultimately intended to be replaced by the Joint Advisor Investment Advisory Agreement and will terminate upon the effectiveness of the Joint Advisor Investment Advisory Agreement, and (ii) why the Company’s stockholders are being asked to approve both of the proposals.

In response to the Staff’s comment, the Company has revised the disclosure in the Letter to Stockholders and the Notice of Special Meeting of Stockholders and has made conforming revisions throughout the Definitive Proxy Statement.

Ms. Jaea Hahn January 18, 2018 Page 2

2.    Please provide appropriate cross-references (to the extent applicable) to the materials filed by the Company on Schedule 14A as definitive additional materials subsequent to the filing of the Proxy Statement (the “DEFA Materials”), and consider stating that the Company’s stockholders should read the Proxy Statement in conjunction with such materials.

In response to the Staff’s comment, the Company has revised the disclosure in the Q&A “Why am I receiving these materials?” on page 1 of the Definitive Proxy Statement.

Information about the Special Meeting and the Vote

Page 1, 2: “Why am I being asked to approve the Investment Co-Advisory Agreements Proposal and the Joint Advisor Investment Advisory Agreement Proposal?”

3.    Please include additional information from the DEFA Materials on the proposed relationship between affiliates of FS Investments, including FSIC III Advisor, and KKR Credit with respect to the business development companies (“BDCs”) that they advise or sub-advise in order to provide more background.

In response to the Staff’s comment, the Company has revised the disclosure in this Q&A on pages 2 and 3 of the Definitive Proxy Statement and has made conforming revisions throughout the Definitive Proxy Statement.

4.    Please include additional information from the DEFA Materials regarding GDFM’s resignation as sub-adviser to the Company and disclose whether GDFM will receive compensation outside of the fees payable to GDFM by FSIC III Advisor under the Current Investment Sub-Advisory Agreement in connection with such resignation and its agreement to cooperate with FSIC III Advisor in implementing the transition of investment advisory services.

In response to the Staff’s comment, the Company has revised the disclosure in this Q&A on pages 2 and 3 of the Definitive Proxy Statement and has made conforming revisions throughout the Definitive Proxy Statement.

5.    Please supplementally confirm that the Company believes that there is no breach of GDFM’s fiduciary duty to the Company’s stockholders under Section 36(a) of the 1940 Act in connection with GDFM’s receipt of payment in connection with its resignation as sub-adviser to the Company and agreement to cooperate with FSIC III Advisor in implementing the transition of investment advisory services.

Ms. Jaea Hahn January 18, 2018 Page 3

The Company supplementally confirms that, due to the nature and source of such payment, which shall be made by FS Investments or one of its affiliates (but not, for the avoidance of doubt, the Company, FSIC, FSIC II or FSIC IV), the Company believes that GDFM’s receipt of such payment in connection with its resignation as sub-adviser to the Company and agreement to cooperate with FSIC III Advisor in implementing the transition of investment advisory services will not violate GDFM’s fiduciary duty to the Company’s stockholders under Section 36(a) of the 1940 Act. Furthermore, in order to qualify for the safe harbor under Section 15(f) of the 1940 Act, FSIC III Advisor has agreed to use its reasonable best efforts to cause any new adviser, co-adviser or sub-adviser to the Company to take such actions so that (i) for a period of three years following GDFM’s resignation, at least 75% of the directors on the Board are not (A) “interested persons” of any investment adviser of the Company on or after such resignation date or (B) “interested persons” of the person who was the investment adviser of the Company immediately prior to such resignation date and (ii) for a period of two years following GDFM’s resignation, there shall not be imposed on the Company an “unfair burden,” as a result of the transactions contemplated by the Transition Agreement, or any terms, conditions or understandings applicable thereto.

6.    Please clarify that the investment advisory agreements to be entered into pursuant to the Investment Co-Advisory Agreements Proposal, on the one hand, and the Joint Advisor Investment Advisory Agreement Proposal, on the other hand, will not be in effect at the same time and that, if approved by the Company’s stockholders, the Investment Co-Advisory Agreements will remain in effect only until the Joint Advisor Investment Advisory Agreement, if approved, becomes effective. Please revise this section to discuss the two proposals separately.

In response to the Staff’s comment, the Company has revised the disclosure in this Q&A on page 4 of the Definitive Proxy Statement and has made conforming revisions throughout the Definitive Proxy Statement.
