Barry Sullivan (August 29, 1912 – June 6, 1994) was an American movie actor who appeared in over 100 movies from the 1930s to the 1980s.

Born in New York City, the seventh son of a seventh son, Sullivan fell into acting when in college playing semi-pro football. During the later Depression years, Sullivan was told that because of his 6 ft 3 in (1.9 m) stature and rugged good looks he could "make money" simply standing on a Broadway stage. This began an extremely successful career on Broadway, movies and television, culminating in 1955 in the role of "Defense Attorney Greenwald". For episode "The Caine Mutiny Court-Martial".

One of Sullivan's most memorable roles was playing a movie director in The Bad and the Beautiful opposite Kirk Douglas. Sullivan starred in movies with Joan Crawford, Loretta Young, and most of the forties and fifties leading ladies. Sullivan toured the US with Bette Davis in theatrical readings of the poetry of Carl Sandburg and starred opposite her in the 1951 film Payment on Demand.
