Dear Sirs

Baiya International Group Inc. (the Company)

We have acted as Cayman Islands counsel to the Company in connection with the Company’s registration statement on Form F-1, including all amendments or supplements thereto (the Registration Statement), as filed with the United States Securities and Exchange Commission (the Commission) under the United States Securities Act 1933, as amended (the Act). The Registration Statement relates to the offering (the Offering) of up to 3,000,000 ordinary shares of a par value of US$0.0001 each of the Company (the Ordinary Shares), plus an option to issue up to an additional 450,000 Ordinary Shares to be offered by the Company pursuant to the Offering to cover the over-allotment option to be granted to the underwriters (collectively, the IPO Shares). In addition, there will be a resale by certain selling shareholders of the Company as stated in the Registration Statement (collectively, the Selling Shareholders) of up to 1,500,000 Ordinary Shares which are presently issued and outstanding (the Resale Shares). We are furnishing this opinion as Exhibit 5.1 to the Registration Statement.

Unless a contrary intention appears, all capitalised terms used in this opinion have the respective meanings set forth in the Documents. A reference to a Schedule is a reference to a schedule to this opinion and the headings herein are for convenience only and do not affect the construction of this opinion.

3 Opinions

On the basis of the examinations and assumptions referred to above and subject to the limitations and qualifications set forth in paragraph 4 below, we are of the opinion that:

Corporate status

(a) The Company has been duly incorporated as an exempted company with limited liability under the Companies Act (Revised) (Companies Act) of the Cayman Islands and is validly existing and in good standing with the Registrar.

Authorised Share capital

(b) The authorised share capital of the Company is US$50,000 divided into (i) 400,000,000 Ordinary Shares of US$0.0001 par value each and (ii) 100,000,000 Preferred Shares of US$0.0001 par value each.

Valid Issuance of shares

(c) The Company has the capacity and power to exercise its rights and perform its obligations under the Registration Statement.

(d) The issuance and allotment of the IPO Shares have been duly authorised and, when issued and allotted in accordance with the Registration Statement and the duly passed Board Resolutions and once consideration is paid for in accordance with the Registration Statement, will be validly issued, fully paid and non-assessable. Once the register of members of the Company has been updated to reflect the issuance, the shareholders recorded in the register of members will be deemed to have legal title to the IPO Shares set against their respective name.

(e) The Resale Shares being proposed for resale by the Selling Shareholders have been validly issued, fully paid and non-assessable.

Registration Statement - Taxation

(f) The statements contained in the Registration Statement in the section headed “Cayman Islands Taxation”, in so far as they purport to summarise the laws or regulations of the Cayman Islands, are accurate in all material respects and that such statements constitute our opinion.

4 Limitations and Qualifications

4.1 We offer no opinion:

(a) as to any laws other than the laws of the Cayman Islands, and we have not, for the purposes of this opinion, made any investigation of the laws of any other jurisdiction, and we express no opinion as to the meaning, validity, or effect of references in the Documents to statutes, rules, regulations, codes or judicial authority of any jurisdiction other than the Cayman Islands; or

Page 4 of 4

(b) except to the extent that this opinion expressly provides otherwise, as to the commercial terms of, or the validity, enforceability or effect of the Registration Statement, the accuracy of representations, the fulfilment of warranties or conditions, the occurrence of events of default or terminating events or the existence of any conflicts or inconsistencies among the Registration Statement and any other agreements into which the Company may have entered or any other documents.

4.2 Under the Companies Act (Revised) (Companies Act) of the Cayman Islands annual returns in respect of the Company must be filed with the Registrar of Companies in the Cayman Islands, together with payment of annual filing fees. A failure to file annual returns and pay annual filing fees may result in the Company being struck off the Register of Companies, following which its assets will vest in the Financial Secretary of the Cayman Islands and will be subject to disposition or retention for the benefit of the public of the Cayman Islands.

4.3 In good standing means only that as of the date of this opinion the Company is up-to-date with the filing of its annual returns and payment of annual fees with the Registrar of Companies. We have made no enquiries into the Company’s good standing with respect to any filings or payment of fees, or both, that it may be required to make under the laws of the Cayman Islands other than the Companies Act.

5 Governing law of this opinion

5.1 This opinion is:

(a) governed by, and shall be construed in accordance with, the laws of the Cayman Islands;

(b) limited to the matters expressly stated in it; and

(c) confined to, and given on the basis of, the laws and practice in the Cayman Islands at the date of this opinion.

5.2 Unless otherwise indicated, a reference to any specific Cayman Islands legislation is a reference to that legislation as amended to, and as in force at, the date of this opinion.

6 Reliance

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the headings “Enforceability of Civil Liabilities”; “Taxation” and “Legal Matters” of the Registration Statement. In providing our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the Rules and Regulations of the Commission thereunder.

This opinion may be used only in connection with the offer and sale of the IPO Shares while the Registration Statement is effective.

Yours faithfully

/s/ Ogier
