Re: Post-Effective Amendment No. 8 - Triangle Capital Corporation (File No. 812-00733)

Dear Mr. Parachkevov:

On behalf of Triangle Capital Corporation (“Triangle” or the “Company”), and in response to an oral comment received from the staff of the Division of Investment Management (the “Staff”) of the Securities and Exchange Commission (the “Commission”) on July 9, 2014 (the “Comment”) relating to Post-Effective Amendment No. 8 (“PEA 8”) to the Company’s Registration Statement filed on Form N-2 on June 27, 2014, we submit this letter containing the Company’s responses to the Staff’s Comment.

Legal Comment

1. Comment: The Staff requested that the Company provide the assumptions upon which it based the decision to reflect only a hypothetical note offering, and not a hypothetical convertible securities offering, in footnote number 5 to the Fee and Expense table on page 8 of PEA 8.

Response: Based on its current understanding of the market and its current expectations of its capital needs, the Company believes that, if and to the extent it offers securities in the next twelve months, it is more likely that they would offer notes similar to existing Senior Notes rather than convertible securities. Thus, they focused the hypothetical on such a potential offering.

****

The Company hereby acknowledges that:

A.The Company is responsible for the adequacy and accuracy of the disclosure in its filings with the Commission;
