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.
