Surf II is a 1984 American comedy film written and directed by Randall M. Badat and starring Eddie Deezen, Linda Kerridge, Eric Stoltz and Jeffrey Rogers. The plot follows two dim-witted surfers attempting to thwart the plans of a mad scientist attempting to rid the beaches of surfers by turning them into zombie punks through chemically-altered soda pop.

A parody of 1960s-style beach party films, Surf II mixes elements of the science fiction, horror, surf and sex comedy genres, featuring a prominent soundtrack comprising both classic surf music and contemporary new wave. Although the film was received negatively by critics upon release, it has since been positively reappraised in cult film circles. In 2021, Vinegar Syndrome released a 2k restoration of the film on Blu-ray.

Despite the title's implication, Surf II is not a sequel and there was never a Surf I. The film was marketed with a number of subheadings, the most common of which was the tongue-in-cheek Surf II: The End of the Trilogy.
