POWER OF ATTORNEY

Know all by these presents, that I hereby constitute and appoint
each of Ben G. Campbell and Troy Renner my true and lawful
attorney-in-fact and agent, each acting alone, with full power
of substitution for me and in my name, place and stead, to:

  1.  execute for me and on my behalf, in my capacity as an officer
and/or director of C.H. Robinson Worldwide, Inc., Forms 3, 4 or 5
in accordance with Section 16(a) of the Securities and Exchange
Act of 1934, as amended, and the rules promulgated thereunder;

  2.  do and hereby perform any and all acts for me and on my
behalf 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 United
States Securities and Exchange Commission and any stock exchange
or similar authority; and

  3.  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 me, in my best interest
or legally required by me, it being understood that
the documents executed by such attorney-in-fact on my behalf
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.

I hereby grant to each such 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 I might or could do if
personally present, 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.
I acknowledge that the attorneys-in-fact, in serving in such
capacity at my request, are not assuming, nor is C.H. Robinson
Worlwide, Inc. assuming, any of my responsibilities to comply
with Section 16 of the Securities and Exchange Act of 1934, as
amended.

This Power of Attorney shall remain in full force and effect
until I am no longer required to file Forms 3, 4 and 5 with
respect to my holdings of and transactions in securities
of C.H. Robinson Worldwide, Inc., unless earlier revoked
by me in a signed writing delivered to the attorneys-in-fact
named above.

    IN WITNESS WHEREOF, I have signed this Power of Attorney
on October 10, 2012.
