Leonard Barr (born Leonard Barra; September 27, 1903 – November 22, 1980) was an American stand-up comedian, film actor, and dancer. Barr appeared several times with Dean Martin (his nephew) and Jerry Lewis when they hosted the Colgate Comedy Hour. He had a brief role in The Sting, appropriately as a burlesque comic. That is also the way his character is listed in the credits—as an anonymous comedian. However, in the wings of the stage just before the comic's entrance, he has a brief conversation with Johnny Hooker (Robert Redford), who addresses him as "Leonard".
