Re: Registration Statement on Form S-3 (333-281813)

Ladies and Gentlemen:

We have acted as counsel to Trio Petroleum Corp, a Delaware corporation (the “Company”), in connection with the above-referenced registration statement (the “Registration Statement”), the base prospectus dated September 10, 2024 (the “Base Prospectus”), the prospectus supplement dated January 9, 2026 (the “Prospectus Supplement”), Amendment No. 1 to the Prospectus Supplement, dated March 3, 2026 (“ Amendment No. 1”), Amendment No 2 to the Prospectus Supplement, dated March 4, 2026 (“Amendment No. 2”), and Amendment No. 3 to the Prospectus Supplement, dated March 5, 2026 (“Amendment No. 3” and together with Amendment No. 2, Amendment No. 1, the Prospectus Supplement and the Base Prospectus, the “Prospectus”), relating to the offering by the Company of up to $4,000,000 of shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (“Common Stock”). The Shares are covered by the Registration Statement and we understand that the Shares are to be offered and sold in the manner described in the Prospectus. This opinion is being delivered at the request of the Company and in accordance with the requirements of Item 601(b)(5) of Regulation S-K promulgated by the Securities and Exchange Commission (the “Commission”).

For purposes of this opinion, we have examined such documents and reviewed such questions of law as we have considered necessary and appropriate for the purposes of our opinion set forth below. In rendering our opinion, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures and the conformity to authentic originals of all documents submitted to us as copies. We have also assumed the legal capacity for all purposes relevant hereto of all natural persons and, with respect to all parties to agreements or instruments relevant hereto other than the Company, that such parties had the requisite power and authority (corporate or otherwise) to execute, deliver and perform such agreements or instruments, that such agreements or instruments have been duly authorized by all requisite action (corporate or otherwise), executed and delivered by such parties and that such agreements or instruments are the valid, binding and enforceable obligations of such parties. As to questions of fact material to our opinions, we have relied upon certificates of officers of the Company and of public officials.

Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized and, when issued and paid for as described in the Prospectus, will be validly issued, fully paid and non-assessable,.

We express no opinion as to matters governed by any laws other than the Delaware General Corporation Law, the laws of the State of New York and the federal laws of the United States of America, all as in effect on the date hereof.

We consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Company’s Current Report on Form 8-K filed on March 5, 2026, which is incorporated by reference in the Prospectus. We also consent to the reference of our firm under the caption “Experts” in the Prospectus and in each case in any amendment or supplement thereto. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 and Section 11 of the Securities Act of 1933, as amended, or the rules and regulations of the Commission promulgated thereunder, nor do we admit that we are experts with respect to any part of the Prospectus within the meaning of the term “expert” as used in the Securities Act of 1933, as amended, or the related rules and regulations of the Commission promulgated thereunder.

Very truly yours,
