POWER OF ATTORNEY
The undersigned hereby constitutes and appoints each of John M. Donnan, Cherrie
I. Tsai and Kiersten Severson, or any of them, signing singly, the undersigned's
true and lawful attorney-in-fact to:
1. to the extent the undersigned does not have the access codes necessary to
file on EDGAR, execute for and on behalf of the undersigned a Form ID and any
other form required to be filed or submitted in accordance with Regulation S-T
promulgated by the United States Securities and Exchange Commission (the
"Commission") in order to obtain such codes; and
2. execute for and on behalf of the undersigned, in the undersigned's capacity
as an officer and/or director of Kaiser Aluminum Corporation (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 that may
be necessary or desirable to complete and execute any such Form ID or Form 3, 4
or 5 and timely file any such form or forms with the Commission and any stock
exchange or similar authority; and
4. take any other action of any type whatsoever in connection with the foregoing
that, 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 sole discretion.
The undersigned hereby grants to each such attorney-in-fact and any of them full
power and authority to do and perform any and every act and thing whatsoever,
necessary or desirable 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 any such attorney-in-fact,
or any 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 acknowledges that none of the foregoing
attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16 of the Securities Exchange Act of
1934.
The execution by the undersigned of this power of attorney hereby expressly
revokes and terminates any powers of attorney previously granted by the
undersigned with respect to a Form ID or Forms 3, 4 and 5 involving Company
securities.  This power of attorney shall remain in full force and effect until
the undersigned is no longer required to file a Form ID or 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 attorneys-in-fact.
IN WITNESS WHEREOF, the undersigned has caused this power of attorney to be
