Douglas Elton Fairbanks Jr. (December 9, 1909 – May 7, 2000) was an American actor, producer, and United States Navy officer. He was a leading man during the Golden Age of Hollywood, notably in adventure and swashbuckling roles like in The Prisoner of Zenda (1937), Gunga Din (1939), and The Corsican Brothers (1941). He was the son of Douglas Fairbanks and the stepson of Mary Pickford, and his first marriage was to actress Joan Crawford, who "picked up his father's swashbuckling style and later cut a dash in high society and royal circles."

Fairbanks was a decorated Naval officer during the Second World War, overseeing the Beach Jumpers special warfare unit. For his war service, he received several military accolades including the Silver Star, the Legion of Merit, the French Legion of Honour and Croix de Guerre, and the British Distinguished Service Cross.
