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. Examples of comedy horror films include Abbott and Costello Meet Frankenstein (1948), An American Werewolf in London (1981), the Evil Dead franchise (1981–present), Gremlins (1984), Shaun of the Dead (2004), and The Cabin in the Woods (2011).

Black comedy, also known as dark comedy, morbid humor, gallows humor, black humor, or dark humor, is a style of comedy that makes light of subject matter that is generally considered taboo, particularly subjects that are normally considered serious or painful to discuss. Writers and comedians often use it as a tool for exploring vulgar issues by provoking discomfort, serious thought, and amusement for their audience. Thus, in fiction, for example, the term black comedy can also refer to a genre in which dark humor is a core component. Cartoonist Charles Addams was famous for such humor, e.g. depicting a boy decorating his bedroom with stolen warning signs including "NO DIVING – POOL EMPTY", "STOP – BRIDGE OUT" and "SPRING CONDEMNED."
