Philip Willis Tone (April 9, 1923 – November 28, 2001) was a United States federal judge.
Born in Chicago, Illinois, Tone received an A.B. from State University of Iowa in 1943 and was a First Lieutenant in the United States Army during World War II, from 1943 to 1946. He received a J.D. from State University of Iowa College of Law in 1948. He was a law clerk to Supreme Court Justice Wiley B. Rutledge from 1948 to 1949. He was then in private practice in Washington, D.C. until 1950, and in Chicago until 1972.
On November 29, 1971, Tone was nominated by President Richard Nixon to a new seat on the United States District Court for the Northern District of Illinois created by 84 Stat. 294. He was confirmed by the United States Senate on December 2, 1971, and received his commission on January 26, 1972.
Just over two years later, on April 22, 1974, Nixon nominated Tone for elevation to a seat on the United States Court of Appeals for the Seventh Circuit vacated by Roger Joseph Kiley. Tone was confirmed by the United States Senate on May 6, 1974, and received his commission on May 14, 1974. Tone served in that capacity until his resignation from the bench, on April 30, 1980.
He then returned to private practice in Chicago until his death, in 2001, in Glenview, Illinois.
