Mickey Simpson (December 3, 1913 – September 23, 1985) was an American supporting actor of burly roles, probably most familiar as "Sarge," the bigoted diner owner in the 1956 film Giant.

He has been referred to in some sources as the 1935 "New York City Heavyweight Boxing Champion," but the only official records of his ring work are for two fights in Los Angeles in 1939, both of which he lost.

Simpson found fairly steady movie work in various roles as guards, cops, bouncers, and thugs until his career was interrupted by World War II, in which he served in the United States Navy as a Shore Patrolman, keeping drunken sailors and townies from killing each other, while patrolling the many L.A. bars and strip clubs.

When he returned to Hollywood, it was Ford who resurrected his career, giving Simpson a small but notable role as one of Walter Brennan's sons in My Darling Clementine.

Simpson appeared as Rocky Duggan in the Three Stooges film Gents in a Jam in which he played a wrestler dubbed "the strongest man in the world."
