        Know all by these presents that the undersigned hereby constitutes and
appoints Ryan A. Murr and Alice Lee as the undersigned's true and lawful
attorney-in-fact to:

    (1) prepare, execute in the undersigned's name and on the undersigned's
        behalf, and submit to the U.S. Securities and Exchange Commission (the
        "SEC") a Form ID, including amendments thereto, and any other documents
        necessary or appropriate to obtain codes, passwords, and passphrases
        enabling the undersigned to make electronic filings with the SEC of
        reports required by the Securities Exchange Act of 1934 or any rule or
        regulation of the SEC;

    (2) execute for and on behalf of the undersigned, in the undersigned's
        capacity as a director of Rocket Pharmaceuticals, Inc. (the "Company"),
        Forms 3, 4, and 5 in accordance with Section 16(a) of the Securities
        Exchange Act of 1934 and the rules thereunder;

    (3) do and perform any and all acts for and on behalf of the undersigned
        which may be necessary or desirable to complete and execute any such
        Form 3, 4, or 5, complete and execute any amendment or amendments
        thereto, and timely file such form with the SEC and any securities
        exchange or similar authority; and

    (4) take any other action of any type whatsoever in connection with the
        foregoing which, in the opinion of such attorney-in-fact, may be of
        benefit to, in the best interest of, or legally required by, the
        undersigned, it being understood that the documents executed by such
        attorney-in-fact on behalf of the undersigned pursuant to this Power of
        Attorney shall be in such form and shall contain such terms and
        conditions as such attorney-in-fact may approve in such attorney-in-
        fact's discretion.

        The undersigned hereby grants to the attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such attorney-in-fact, or such
attorney-in- fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this power of attorney and the rights and powers herein
granted.  The undersigned also ratifies hereby any action previously taken by
the attorney-in- fact that would have been authorized by this power of attorney
if it has been in effect at the time such action was taken.  The undersigned
acknowledges that the foregoing attorney-in-fact, in serving in such capacity at
the request of the undersigned, is not assuming, nor is the Company assuming,
any of the undersigned's responsibilities to comply with Section 16 of the
Securities Exchange Act of 1934, as amended.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorney-in-fact.

        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be  executed as of April 2, 2018.
