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.

To modern audiences, Griffith is known primarily for directing the 1915 film The Birth of a Nation. One of the most financially successful films of all time and considered a landmark by film historians, it has been denounced for its degrading portrayals of African Americans, its glorification of the Ku Klux Klan, and support for the Confederacy. The film led to riots in several major cities all over the United States and the NAACP attempted to have it banned. Griffith made his next film Intolerance (1916) as an answer to critics, who he felt unfairly maligned his work.

Together with Charlie Chaplin, Mary Pickford, and Douglas Fairbanks, Griffith founded the studio United Artists in 1919 with the goal of enabling actors and directors to make films on their own terms, as opposed to the terms of commercial studios. Several of Griffith's later films were 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 nearly 520 films, including nearly 480 short movies, by the time of The Struggle (1931), his final feature. All but three were completely silent.
