Re:		Horizon Technology Finance Corporation
		Preliminary Proxy Statement on Schedule 14A, Filed May 20, 2011
		File No. 814-00802

Dear Mr. O’Connor:

     On behalf of Horizon Technology Finance Corporation, a Delaware corporation (the “Company”), we are responding to the comments of the staff (the “Staff”) of the Securities and Exchange Commission (the “Commission”) communicated to us by telephone on May 26, 2011 with respect to the above-referenced preliminary proxy statement (the “Preliminary Proxy Statement”). Thank you for your comment which we restate below, followed by the Company’s response.

     In connection with this response, the Company is today filing with the Commission a definitive proxy statement which reflects the response set forth below.

     1. We note the examples of the level of NAV dilution that would be experienced by a nonparticipating stockholder in three different hypothetical stock offerings of different sizes and levels of discount from NAV per share in the section entitled “Examples of Dilutive Effect of the Issuance of Shares Below NAV” beginning on page 9 of the preliminary proxy statement. If the Company’s board of directors would consider approving an offering of the Company’s common stock at a discount to NAV that is greater than the largest discount from NAV reflected in such examples, please accordingly expand the disclosure.

     In response to the Staff’s comment, the Company has accordingly expanded the disclosure on page 10 of the Preliminary Proxy Statement.

     We appreciate the efforts of the Staff in reviewing the preliminary proxy statement and we hope that you find the Company’s responses to the Staff’s comments satisfactory. Please contact Stephen C. Mahon at 513-361-1230 or Toby D. Merchant at 513-361-1229 if you have any questions.
