5 Card Stud is a 1968 American Western mystery film, directed by Henry Hathaway and starring Dean Martin and Robert Mitchum.

In 1880, a gambler in the small town of Rincon, 100 miles (161 km) from Denver, Colorado, is caught cheating at a five-card stud poker game.

5 Card Stud brought together director Henry Hathaway and Dean Martin for a second time; the first was the 1965 film The Sons of Katie Elder starring John Wayne.

In a contemporary review for The New York Times, critic Vincent Canby identified 5 Card Stud as one of a recent spate of "Buddy System" Westerns, such as: El Dorado (1966) with John Wayne and Mitchum; The Way West (1967) with Kirk Douglas, Mitchum and Richard Widmark; The War Wagon (1967) with John Wayne and Kirk Douglas; Bandolero!

"[2] In the Chicago Sun-Times, critic Roger Ebert wrote: "'Five Card Stud' is not a great movie, but it's a polished, professional one, and it's a good deal more than a common Western.
