3 Dev Adam (Üç Dev Adam; translated as Three Giant Men and sometimes referred to as El Santo Y Capitan America Contra Spider-Man or Captain America and Santo Vs. Spider-Man) is a 1973 Turkish superhero film, directed by T. Fikret Uçak and written by Doğan Tamer, based on characters created by Steve Ditko, Jack Kirby, Stan Lee, Joe Simon and Rodolfo Guzmán Huerta, featuring Aytekin Akkaya as Captain America and Yavuz Selekman as El Santo called to Istanbul on a special mission to stop the villainous Spider-Man and his criminal gang.

The Turksploitation film, which went on nationwide general release across the country on November 1, 1973 (1973-11-01), was completely unauthorized by the copyright owners of the characters depicted. The film was popular and thus spawned other rip-offs of other major Hollywood productions.
