Uncle Sam is a 1996 American black comedy slasher film directed by William Lustig, written by Larry Cohen, and starring Isaac Hayes.

In the film, Sam Harper is killed by friendly fire during a military operation in Kuwait. His corpse is returned to his family in time for the Independence Day celebrations, but then returns to life as a revenant. Sam dresses himself in an Uncle Sam costume and goes on a killing spree. His widow and his sister inform Sam's nephew that Sam was a psychopath in life, and that he joined the military in hopes of satisfying his bloodlust. Meanwhile, Sam blames his former mentor for glorifying war in his tales, and for inspiring him to join the military.
