Treehouse of Horror

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.^[a] Each segment involves the Simpson family in some comical horror, science fiction, or supernatural setting; plot elements operate beyond the show's normal continuity, with segments exaggeratedly more morbid and violent than a typical Simpsons episode. 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.

The eponymous first installment "Treehouse of Horror" aired on October 25, 1990, during the second season, broadly inspired by EC Comics horror tales. In addition to parodies of horror, science fiction, and fantasy films, episodes include the recurring alien characters Kang and Kodos, unique opening sequences, and 'scary' pseudonyms in the credits. Treehouse of Horror episodes have earned high ratings and broad popularity, spawning a steady stream of merchandise, including a comic book series that ran from 1995 to 2017.
