Comedy horror, also known as horror comedy, is a literary, television, and film genre that combines elements of comedy and horror fiction. Comedy horror has been described as able to be categorized under three types: "black comedy, parody and spoof." It often crosses over with the black comedy genre. Comedy horror can also parody or subtly spoof horror clichés as its main source of humour or use those elements to take a story in a different direction, for example in The Cabin in the Woods, Tucker & Dale vs. Evil, Shaun of the Dead or the Evil Dead franchise.
Author Bruce G. Hallenbeck cites the short story "The Legend of Sleepy Hollow" by Washington Irving as "the first great comedy horror story". The story made readers "laugh one moment and scream the next" and its premise was based on mischief typically found during the holiday Halloween.
