Jack Edward Tanner (January 28, 1919 – January 10, 2006) was a United States federal judge.
Born in Tacoma, Washington, Tanner was in the United States Army during World War II, from 1943 to 1945. He received an LL.B. from the University of Washington School of Law in 1955. He was in private practice in Tacoma from 1955 to 1978.
On January 20, 1978, Tanner was nominated by President Jimmy Carter to a jointly appointed seat on the United States District Court for the Eastern District of Washington and the United States District Court for the Western District of Washington, both vacated by William N. Goodwin. Tanner was confirmed by the United States Senate on May 17, 1978, and received his commission on May 19, 1978. On November 8, 1978, Tanner was reassigned to the Western District alone. He assumed senior status on January 28, 1991, serving in that capacity until his death, in 2006, in Tacoma.
