Tarzan the Fearless is a 12 chapter American Pre-Code film serial starring Buster Crabbe in his only appearance as Tarzan. It was also released as a 61-minute feature film which consisted of the first four chapters edited together, and which was intended to be followed on a weekly basis by the last eight chapters in individual episode format, but which was often exhibited instead as a stand-alone feature film. Actress Jacqueline Wells co-starred; she later changed her name to Julie Bishop. The serial was produced by Sol Lesser, written by Basil Dickey, George Plympton and Walter Anthony, and directed by Robert F. Hill. The film was released in both formats on August 11, 1933.

Clarence Linden Crabbe II, better known by his nickname Buster Crabbe, was an American two-time Olympic swimmer and film and television actor. He won the 1932 Olympic gold medal for 400-meter freestyle swimming event, which launched his career on the silver screen and later television. He starred in a variety of popular feature films and movie serials released between 1933 and the 1950s, portraying the top three syndicated comic-strip heroes of the 1930s: Tarzan, Flash Gordon, and Buck Rogers.
