To the addressee referred to above:

We are acting as counsel to DigitalBridge Group, Inc., a Maryland corporation (the “Company”), in connection with its registration statement on Form S-3 (the “Registration Statement”), filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”) relating to the resale from time to time on a delayed or continuous basis by the selling securityholders identified in one or more supplements to the prospectus which form part of the Registration Statement, of up to 8,236,140 shares of Class A Common Stock, par value $0.01 per share of the Company (the “Shares”), that were issued to such selling securityholders upon exchange of 5.75% Exchangeable Senior Notes due 2025 (the “Notes”), issued by DigitalBridge Operating Company, LLC (formerly known as Colony Capital Operating Company, LLC) (the “Issuer”) pursuant to the Indenture,dated as of July 21, 2020 (the “Indenture”), between the Issuer, the Company and The Bank of New York Mellon, as trustee. This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. § 229.601(b)(5), in connection with the Registration Statement.

For purposes of this opinion letter, we have examined copies of such agreements, instruments and documents as we have deemed an appropriate basis on which to render the opinions hereinafter expressed. In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to us, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to us as copies (including pdfs). We also have assumed that the Shares will not be issued in violation of the ownership limit contained in the Company’s articles of amendment and restatement, as amended and the amended and restated bylaws of the Company. As to all matters of fact, we have relied on the representations and statements of fact made in the documents so reviewed, and we have not independently established the facts so relied on. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

This opinion letter is based as to matters of law solely on the Maryland General Corporation Law, as amended. We express no opinion herein as to any other statutes, rules or regulations.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Shares are validly issued, fully paid and nonassessable.

This opinion letter has been prepared for use in connection with the Registration Statement. We assume no obligation to advise of any changes in the foregoing subsequent to the effective date of the Registration Statement.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Registration Statement and to the reference to this firm under the caption “Legal Matters” in the prospectus constituting a part of the Registration Statement.
