Clarence Linden Crabbe II (; February 7, 1908 - April 23, 1983), commonly known by his stage name Buster Crabbe, was an American two-time Olympic swimmer and movie actor. He won the 1932 Olympic gold medal for 400-meter freestyle swimming event, which launched his career onto the silver screen. He starred in a number of popular films in the 1930s and 1940s. He also played the title role in the serials Tarzan the Fearless, Flash Gordon and Buck Rogers.

In some movies he is credited as "Larry Crabbe" or "Larry (Buster) Crabbe". Crabbe's role in the Tarzan serial, Tarzan the Fearless (1933), began a career in which he starred in more than a hundred movies. In King of the Jungle (1933), Jungle Man (1941), and the serial King of the Congo (1952), he played typical "jungle man" roles. He starred in several popular films at this time, including The Sweetheart of Sigma Chi alongside Betty Grable (1933) and Search for Beauty (1934).  In 1936 he was picked over several stars to play Flash Gordon in the very successful Flash Gordon serial, followed by two sequels, released by Universal in 1938 and 1940. The series was shown later extensively on American television in the 1950s and 1960s, then edited for release on home video. He also starred as Buck Rogers for Universal playing the role with dark hair unlike Flash Gordon's blonde hair. In 1939, Crabbe reunited with Betty Grable for a lead role in the mainstream comedy Million Dollar Legs.  Crabbe starred at the Billy Rose's Aquacade at the New York World's Fair in its second year of 1940, replacing a fellow Olympic swimmer and Tarzan actor Johnny Weissmuller.  During World War II Crabbe was contracted to Producers Releasing Corporation in lead roles from 1942-1946 where he portrayed a Western folk-hero version of Billy the Kid in 13 films and 23 as Billy Carson with his sidekick played by actor Al St. John. As a 34 year old married man, Crabbe had a deferment from the draft but made Army training films for the field artillery at Ft. Sill, Oklahoma along with Fuzzy St. John. Crabbe also played some jungle roles for the studio.  Following the war Crabbe appeared opposite Weissmuller as a rival in two jungle films, Swamp Fire (1946) and Captive Girl (1950). Crabbe returned to the jungle for his final serial playing the role of Thun'da in King of the Congo (1952).
