A*P*E, released in South Korea as King Kong's Great Counterattack (Korean: 킹콩의 대역습; RR: King Kong eui daeyeokseup), is a 1976 monster film. An international co-production between South Korea and the United States, the film was produced by Kukje Movies and the Lee Ming Film Co. (South Korea) and Worldwide Entertainment (U.S.) with 3-D effects. Directed by Paul Leder and featuring special effects by Park Kwang Nam, the film stars Joanna Kerns, Rod Arrants and Alex Nicol. It marked an early film appearance by Kerns, who later moved to TV movies and series.

A*P*E was released at approximately the same time as Dino De Laurentiis' 1976 remake of King Kong. The film is generally regarded by some critics as a campy Z movie. In later years, the film has gone under the titles of Attack of the Giant Horny Gorilla (for its 1982 grindhouse re-release), and Hideous Mutant (for its original home video release).
