Dear Sirs,
BeyondSpring Inc.
We have acted as Cayman Islands legal advisers to BeyondSpring Inc. (the "Company") in connection with the Company’s registration statement on Form S-3, including all amendments or supplements thereto, filed with the Securities and Exchange Commission (the '"SEC") under the U.S. Securities Act of 1933 on 13 August 2025, as amended to date (the "Registration Statement") relating to the offering by the Company of certain ordinary shares of par value US$0.0001 each (the "Shares").
We are furnishing this opinion as Exhibits 5.1 and 23.1 to the Registration Statement.
| 1 | Documents Reviewed |
For the purposes of this opinion, we have reviewed only originals, copies or final drafts of the following documents:
| 1.1 | The certificate of incorporation of the Company dated 21 November 2014. |
| 1.2 | The amended and restated memorandum and articles of association of the Company as conditionally adopted by a special resolution passed on 24 February 2017 and effective immediately prior to the completion of the Company’s initial public offering of the Shares (the "Memorandum and Articles"). |
| 1.3 | The written resolutions of the board of directors of the Company (the "Board") dated 29 May 2024 and 30 December 2024 (the "Resolutions"). |
| 1.4 | A certificate from a director of the Company, a copy of which is attached hereto (the "Director's Certificate"). |
| 1.5 | A certificate of good standing dated 4 August 2025, issued by the Registrar of Companies in the Cayman Islands (the "Certificate of Good Standing"). |
| 1.6 | The Registration Statement. |
| 2 | Assumptions |
The following opinions are given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion letter. These opinions only relate to the laws of the Cayman Islands which are in force on the date of this opinion letter. In giving these opinions we have relied (without further verification) upon the completeness and accuracy of the Director's Certificate and the Certificate of Good Standing. We have also relied upon the following assumptions, which we have not independently verified:
| 2.1 | Copies of documents, conformed copies or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals, and translations of documents provided to us are complete and accurate. |
| 2.2 | All signatures, initials and seals are genuine. |
| 2.3 | There is nothing under any law (other than the law of the Cayman Islands), and there is nothing contained in the minute book or corporate records of the Company (which we have not inspected), which would or might affect the opinions set out below. |
| 3 | Opinion |
Based upon the foregoing and subject to the qualifications set out below and having regard to such legal considerations as we deem relevant, we are of the opinion that:
| 3.1 | The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands. |
| 3.2 | The authorised share capital of the Company is US$50,000 divided into 500,000,000 ordinary shares of a par value of US$0.0001 each. |
| 3.3 | When (i) the Board has taken all necessary corporate action to approve the issue thereof, the terms of the offering thereof and related matters; (ii) the issue of such Shares has been recorded in the Company's register of members (shareholders); and (iii) the subscription price of such Shares (being not less than the par value of the Shares or Preferred Shares, as the case may be) has been fully paid in cash or other consideration approved by the Board, the Shares will be duly authorised, validly issued, fully paid and non-assessable. |
| 2 |
| 4 | Qualifications |
In this opinion the phrase "non-assessable" means, with respect to shares in the Company, that a shareholder shall not, solely by virtue of its status as a shareholder and in absence of a contractual arrangement, or an obligation pursuant to the memorandum and articles of association, to the contrary, be liable for additional assessments or calls on the shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).
Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions the subject of this opinion.
We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our name under the headings "Enforcement of Civil Liabilities" and "Legal Matters" and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.
Yours faithfully

Dear Sirs
BeyondSpring Inc. (the "Company")
I, the undersigned, being a director of the Company, am aware that you are being asked to provide a legal opinion (the "Opinion") in relation to certain aspects of Cayman Islands law. Capitalised terms used in this certificate have the meaning given to them in the Opinion. I hereby certify that:
| 1 | The Memorandum and Articles remain in full and effect and are unamended. |
| 2 | The Board Resolutions were duly passed in the manner prescribed in the Memorandum and Articles (including, without limitation, with respect to the disclosure of interests (if any) by directors of the Company) and have not been amended, varied or revoked in any respect. |
| 3 | The authorised share capital of the Company is US$50,000 divided into 500,000,000 ordinary shares of a par value of US$0.0001 each. |
| 4 | The shareholders of the Company have not restricted or limited the powers of the directors in any way and there is no contractual or other prohibition (other than as arising under Cayman Islands law) binding on the Company prohibiting it from issuing and allotting the Shares or otherwise performing its obligations under the Registration Statement. |
| 5 | The directors of the Company at the date of the Board Resolutions and at the date hereof were and are as follows: |
Lan Huang
Brendan Delaney
Patrick Fabbio

| 6 | Each director considers the transactions contemplated by the Registration Statement to be of commercial benefit to the Company and has acted in good faith in the best interests of the Company, and for a proper purpose of the Company, in relation to the transactions the subject of the Opinion. |
| 2 |
| 7 | To the best of my knowledge and belief, having made due inquiry, the Company is not the subject of legal, arbitral, administrative or other proceedings in any jurisdiction that would have a material adverse effect on the business, properties, financial condition, results of operations or prospects of the Company and neither the directors nor Shareholders have taken any steps to have the Company struck off or placed in liquidation. Further, no steps have been taken to wind up the Company or to appoint restructuring officers or interim restructuring officers, and no receiver has been appointed in relation to any of the Company’s property or assets. |
I confirm that you may continue to rely on this Certificate as being true and correct on the day that you issue the Opinion unless I shall have previously notified you personally to the contrary.
