The Boat is a 1921 American two-reel silent comedy film written and directed by, and starring Buster Keaton. Contemporary reviews consider it one of his best shorts, with One Week (1920), The Playhouse (1921) and Cops (1922). It is presently in the public domain. The International Buster Keaton Society takes its name, The Damfinos, from the name of the film's boat.

Joseph Frank "Buster" Keaton was an American actor, comedian and film director. He is best known for his silent films during the 1920s, in which he performed physical comedy and inventive stunts. He frequently maintained a stoic, deadpan facial expression that became his trademark and earned him the nickname "The Great Stone Face".
