John P. "J.P." Finnegan (August 18, 1926 – July 29, 2012) was an American film and television actor, mostly known for his recurrent role on the American crime fiction series Columbo. He voiced the villainous character Warren T. Rat in the 1986 Don Bluth film An American Tail.
A friend of director/actor John Cassavetes, Finnegan appeared in five of his films, including A Woman Under the Influence (1974), Gloria (1980) and Big Trouble (1986), which also starred Columbo star Peter Falk. He also appeared in Heroes (1977), The Natural (1984), School Spirit (1985), Big Man on Campus (1989) and Come See the Paradise (1990), and portrayed Judge Edward A. Haggerty in Oliver Stone's JFK (1991).
One of 11 children born to Irish immigrant parents, Finnegan served in the United States Navy during World War II. He became friends with Cassavetes and Falk at the Actors Studio in his native New York City. They helped Finnegan in the early 1950s, when he moved to Los Angeles.
Finnegan died on July 29, 2012 at his home in Palm Desert, California from complications of pneumonia, aged 85. He was survived by his second wife, Carolynn, whom he married in 1992, and by his four children by his first wife, who died in 1989.
