The Human Duplicators is a 1965 American science fiction film by Woolner Brothers Pictures Inc. Produced and directed by Hugo Grimaldi and Arthur C. Pierce (the latter uncredited as director), the film stars George Nader, Barbara Nichols, George Macready and Dolores Faith. It was shown in the US on a double feature with Mutiny in Outer Space.

The narrative follows a very tall space alien (Richard Kiel) who has come to earth at the command of the "Intergalactic Council" to replace select humans with "android doppelgängers." The goal of human duplication is to take over the earth, but the plan fails when the androids are destroyed by an investigator from the US National Intelligence Agency.
