Don Dubbins (June 28, 1928 - August 17, 1991), originally Donald Dubbins, was an American actor of film and television who in his early career usually played younger military roles, particularly in such classic pictures as From Here to Eternity (1953) and The Caine Mutiny (1954). Screen giant James Cagney took a liking to Dubbins and procured roles for him in two 1956 films, These Wilder Years and Tribute to a Bad Man. In the former, Dubbins played Cagney's long-lost adopted son; in the latter, he was in a romantic triangle with cattle boss Cagney for the affections of a senorita. In 1957, Dubbins played a callow young United States Marines private in Jack Webb's The D.I. In 1958, Dubbins was cast in From the Earth to the Moon, a science fiction picture based on Jules Verne's novel of the same title.

As Dubbins matured, he appeared in such films as The Prize in 1963, The Illustrated Man (based on a Ray Bradbury novel) in 1969, and Death Wish II in 1982.
