Ladies and Gentlemen:

We have acted as counsel to GRI Bio, Inc., a Delaware corporation (the "***Company***"), with respect to certain matters in connection with the Registration Statement on Form S-3 (File No. 333-279348) (the "***Registration Statement***"), filed with the Securities and Exchange Commission (the "***Commission***") under the Securities Act of 1933, as amended (the "***Act***"), the related prospectus dated May 16, 2024 included within the Registration Statement (the "***Base Prospectus***") and the prospectus supplement dated January 9, 2026, relating to the issue and sale of up to $7,379,813 of shares of the Company's common stock, par value $0.0001 per share (the "***Shares***"), each filed with the Commission pursuant to Rule 424(b) promulgated under the Act (together with the Base Prospectus, the "***Prospectus***"). The Shares are to be sold by the Company in accordance with that certain At the Market Offering Agreement, dated May 20, 2024, between the Company and H.C. Wainwright & Co., LLC (the "***Sales Agreement***"), as described in the Prospectus.

In connection with this opinion, we have examined the Company's Amended and Restated Certificate of Incorporation, as amended to date, and Amended and Restated Bylaws, both as currently in effect, such other records of the corporate proceedings of the Company and certificates of the Company's officers as we have deemed relevant, as well as the Registration Statement and the exhibits thereto and the Prospectus.

In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, photostatic or facsimile copies and the authenticity of the originals of such copies.

Based upon the foregoing, and subject to the limitations set forth below, we are of the opinion that the Shares, when issued by the Company out of the Company's duly authorized common stock and issued and delivered by the Company against payment therefor as contemplated by the Sales Agreement, on terms approved by the Board of Directors of the Company, or a duly authorized committee thereof, will be duly and validly issued, fully paid and nonassessable.

Our opinion is limited to the General Corporation Law of the State of Delaware, and we express no opinion with respect to the laws of any other jurisdiction. No opinion is expressed herein with respect to the qualification of the Shares under the securities or blue sky laws of any state or any foreign jurisdiction.

We have relied as to certain matters on information obtained from public officials, officers of the Company, and other sources believed by us to be responsible.
