Raoul Walsh (11 March 1887 - 31 December 1980) was an American film director.

Walsh started his entertainment career as a stage actor in New York, quickly progressing into film acting. In 1914 he became assistant to D.W. Griffith and worked almost entirely on contract with him at Fox until 1928. At Paramount Pictures in the 1930s he directed stars such as James Cagney, Humphrey Bogart, and Errol Flynn before joining Warner Brothers in the early 1940s. His contact at Warners expired in 1953 and he retired in 1964.

A founding member of the Academy of Motion Picture Arts and Sciences (AMPAS), Walsh lost an eye in a car accident while working on the film In Old Arizona in 1929. He was the brother of actor George Walsh .
