On behalf of Triangle Capital Corporation (the “Registrant”) and pursuant to Rule 461 promulgated under the Securities Act of 1933, as amended, I hereby request acceleration of the effective date of the Registration Statement, including all amendments thereto, to 4:00 p.m. Eastern Time on Thursday, July 23, 2015, or as soon thereafter as is practicable.

The Registrant represents to the U.S. Securities and Exchange Commission (the “Commission”) that should the Commission, or the staff acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing, and the Registrant represents that it will not assert staff comments or the action of the staff to declare the filing effective as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.
