Kenneth Noble "Ken" Sanborn (born November 14, 1926) is a retired Michigan politician and judge best known for successfully defending his friend Milo Radulovich against charges of communism in 1953. The case was a major factor in helping turn public opinion in the United States against McCarthyism.
Ken Sanborn graduated from the University of Detroit Law School in 1949. Sanborn's career as a lawyer was highlighted by the Radulovich trial, which gained national attention. He served as Clinton Township's Justice of the Peace from 1951 to 1956, then was elected State Representative for Macomb County (then the 3rd District) and held that seat in 1957 and 1958. He next served as Clinton Township Supervisor, from 1959 to 1961, and held office as the trustee and chairman of Macomb Community College until 1968.
In 1972, Sanborn became a probate judge in Mount Clemens, and then in 1978 was promoted to circuit judge for Michigan's 16th Circuit Court.
Sanborn served as circuit judge until 1990, when he retired and became a visiting judge for Macomb County.
