"Treehouse of Horror" is the third episode of the second season of the American animated television series The Simpsons. It originally aired on the Fox network in the United States on October 25, 1990. The episode was inspired by 1950s horror comics, and begins with a disclaimer that it may be too scary for children. It is the first Treehouse of Horror episode. These episodes do not obey the show's rule of realism and are not treated as canon. The opening disclaimer and a panning shot through a cemetery with humorous tombstones were features that were used sporadically in the Treehouse of Horror series and eventually dropped. This is also the first episode to have the music composed by Alf Clausen.

Treehouse of Horror is a series of annual Halloween-themed anthology episodes of the animated sitcom The Simpsons. Also known as The Simpsons Halloween Specials, each episode typically consists of three separate, self-contained segments.

With 34 episodes as of 2023, each Treehouse of Horror episode is numbered in Roman numerals, one less than the respective season it is in.
