Beaverton, Oregon 97005-6453

I have acted as counsel for NIKE, Inc. (the “Company”) in connection with the
filing of a Registration Statement on Form S-8 (the “Registration Statement”)
under the Securities Act of 1933, as amended, covering 31,000,000 shares of
Class B Common Stock, no par value (the “Shares”), of the Company issuable in
connection with the Company153s 1990 Stock Incentive Plan (the “Plan”). I have
reviewed the corporate actions of the Company in connection with this matter and
have examined those documents, corporate records, and other instruments I deemed
necessary for the purposes of this opinion.

Based on the foregoing, it is my opinion that:

1. The Company is a corporation duly organized and validly existing under the
laws of the state of Oregon; and

2. The Shares have been duly authorized and, when issued pursuant to the Plan
and in accordance with the resolutions adopted by the Board of Directors of the
Company, will be legally issued, fully paid and nonassessable.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

Very truly yours,

/s/ John F. Coburn III
