Neighbors is a 1981 American black comedy film based on the novel of the same name by Thomas Berger. It was released through Columbia Pictures, was directed by John G. Avildsen, and starred John Belushi, Dan Aykroyd, Cathy Moriarty, and Kathryn Walker. The film takes liberties with Berger's story and features a more upbeat ending. The screenplay of the film is officially credited to Larry Gelbart, although it was extensively rewritten to Gelbart's public disapproval. Released two and a half months before Belushi's death, the film marks his last film performance.

In the film, a middle class-resident of a suburb has increasingly hostile relationships with his two next-door-neighbors. He eventually decides to play a prank on his male neighbor, but unintentionally abandons the neighbor's truck in a swamp. The neighbor retaliates with vandalism. The suburbanite soon realizes that he enjoys this conflict more than the last few decades of his mundane life.
