Dear Sir and Madam:


Re: Can-Fite BioPharma Ltd. – 150,000,000 Ordinary Shares represented by 5,000,000 American Depositary Shares


We have acted as Israeli counsel to Can-Fite BioPharma Ltd. (the “Company”), a company organized under the laws of the State of Israel in connection with the issuance and sale of an aggregate of 150,000,000 ordinary shares, NIS 0.25 par value per share, (the “Ordinary Shares”) represented by 5,000,000 American Depositary Shares (the “ADSs”) comprised of (i) 57,000,000 ordinary shares represented by 1,900,000 ADSs, and (ii) pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 93,000,000 ordinary shares (the “Pre-Funded Warrant Shares”) represented by 3,100,000 ADSs (the “Offered Pre-Funded ADSs”), all being offered by the Company, pursuant to the terms of the Securities Purchase Agreement dated August 11, 2021 between the Company and the investor party thereto. The ADSs are being issued pursuant to a registration statement on Form F-3 (Registration Statement No. 333-220644) (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), the prospectus dated October 9, 2020 and the prospectus supplement dated August 13, 2021, filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations of the Securities Act.


As counsel to the Company in Israel, we have examined copies of the Articles of Association, as amended, of the Company and such corporate records, instruments, and other documents relating to the Company and such matters of law as we have considered necessary or appropriate for the purpose of rendering this opinion. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic originals of all documents submitted to us as copies.


Based on the foregoing, we advise you that in our opinion, the Ordinary Shares underlying the ADSs and the Pre-Funded ADSs underlying the Pre-Funded Warrants are duly authorized, legally issued, fully-paid and non-assessable.


We are members of the Israeli bar, and the opinions expressed herein are limited to questions arising under the laws of the State of Israel, and we disclaim any opinion whatsoever with respect to matters governed by the laws of any other jurisdiction.


We hereby consent to the use of this opinion as Exhibit 5.1 to the Company’s Current Report on Form 6-K to be filed with the Commission on August 16, 2021, which will be incorporated by reference in the Registration Statement, and to the reference to us under the caption “Legal Matters” in the prospectus included in the Registration Statement. In giving such consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.
