Registration Statement on Form S-3 (Registration No. 333-133109)

Ladies and Gentlemen:

We have acted as counsel to Gulfport Energy Corporation, a Delaware corporation (the “Company”), in connection with the preparation and filing by the Company with the Securities and Exchange Commission of a Registration Statement on Form S-3, as amended (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”). The Registration Statement relates to an underwritten public offering of 6,050,000 shares (the “Selling Stockholders’ Shares”) of the Company’s common stock, $0.01 par value per share (“Common Stock”), to be sold by the Selling Stockholders identified in the Registration Statement, and up to 907,500 additional shares of Common Stock to be sold by the Company pursuant to the exercise of an over-allotment option (the “Option Shares” and together with the Selling Stockholders’ Shares, the “Securities”) pursuant to the terms of an underwriting agreement to be entered into by and among the Company, the Selling Stockholders and Johnson Rice & Company L.L.C. on behalf of the several underwriters.

We have examined originals or certified copies of such corporate records of the Company and other certificates and documents of officials of the Company, public officials and others as we have deemed appropriate for purposes of this letter. We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to authentic original documents of all copies submitted to us as conformed and certified or reproduced copies. As counsel to the Company in connection with the preparation and filing of the Registration Statement, we are familiar with the proceedings taken, and with the additional proceedings proposed to be taken, by the Company in connection with the authorization, registration, issuance and sale of the Securities.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth hereinafter, we are of the opinion that (i) the Selling Stockholders’ Shares have been validly issued and are fully paid and non-assessable, and (ii) when the Option Shares have been issued, sold and delivered as described in the Registration Statement, the Option Shares will be validly issued and fully paid and non-assessable.
