David Wark Griffith (January 22, 1875 – July 23, 1948) was an American film director. Considered one of the most influential figures in the history of the motion picture, he pioneered many aspects of film editing and expanded the art of the narrative film.

Griffith's film The Birth of a Nation (1915) made investors a profit, but also attracted much controversy, as it depicted African Americans in a negative light and glorified the Ku Klux Klan. Intolerance (1916) was made as an answer to his critics. Several of Griffith's later films were also successful, including Broken Blossoms (1919), Way Down East (1920), and Orphans of the Storm (1921), but the high costs he incurred for production and promotion often led to commercial failure. He had made roughly 500 films by the time of his final feature, The Struggle (1931).

Together with Charlie Chaplin, Mary Pickford, and Douglas Fairbanks, Griffith founded United Artists, enabling them to control their own interests, rather than depending on commercial studios.
