Tarzan's Hidden Jungle is a 1955 Black & White movie from RKO Pictures starring Gordon Scott in his first film as Tarzan, taking over the role from Lex Barker, who had in turn followed Johnny Weissmuller in the series. This film about Edgar Rice Burroughs' ape-man also features Vera Miles and Jack Elam, and was directed by Harold D. Schuster. It was the last of 12 Tarzan pictures released by RKO.

Tarzan's mate, Jane, does not appear in this film. Tarzan at first seems to show more than casual interest in Miles' character, but ultimately there is no romance. In real life, Scott and Miles were married after the film was completed. Scott eventually played Tarzan in six movies over a five-year span.
