     Re:  Class A Common Stock, $.01 par value per share
          ----------------------------------------------

Ladies and Gentlemen:

     We have acted as special counsel to Hub Group, Inc., a Delaware corporation
(the "Company"), in connection with the registration under the Securities Act of
1933, as amended (the "Securities Act"), of 172,500 shares of its Class A Common
Stock, $.01 par value per share (the "Shares"), that may be purchased pursuant
to a public offering by the Company.  We have also participated in the
preparation and filing with the Securities and Exchange Commission under the
Securities Act of a registration statement on Form S-3 (the "Registration
Statement") relating to the Shares.  In this connection, we have examined such
corporate and other records, instruments, certificates and documents as we
considered necessary to enable us to express this opinion.

     Based upon the foregoing, we are of the opinion that the Shares are duly
authorized for issuance and when issued in accordance with the provisions of the
Registration Statement will be legally issued, fully paid and non-assessable
Shares of the Company.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to us under the caption "Legal Matters."

                                           Very truly yours,

                                           /s/ Mayer, Brown & Platt

                                           MAYER, BROWN & PLATT
