The Stupids is a 1996 adventure comedy film starring Tom Arnold and directed by John Landis. It is based on The Stupids, characters from a series of books written by Harry Allard and illustrated by James Marshall. It was largely panned by critics and was a commercial failure.

The film follows the fictional family, the Stupids, with a last name synonymous with their behavior. The story begins with patriarch Stanley Stupid believing "sender" from letters marked "return to sender" is a wicked man planning a conspiracy. Adding several misunderstandings, they unwittingly save the world from military chaos, while believing a fake story about a fictional man named Sender and his plot to confiscate everyone's mail and garbage.
