Shock Waves is a 1977 American horror film written and directed by Ken Wiederhorn. The film is about a group of tourists who encounter aquatic Nazi zombies when they become shipwrecked. It stars Peter Cushing as a former SS commander, Brooke Adams as a tourist, and John Carradine as the captain of the tourists' boat.

Nazi zombies are a horror trope found in films, video games, and comic books. Nazi zombie narratives usually feature undead Nazi soldiers resurrected to fight for the Third Reich. The book Nazisploitation!: The Nazi Image in Low-Brow Cinema and Culture described the genre as a small theme of horror films.
