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, An American Werewolf in London 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. 
Horror and comedy have been associated with each other since the early days of horror novels. Shortly after the publication of Mary Shelley's Frankenstein , comedic parodies appeared. Edgar Allan Poe put humor and horror on the same continuum, and many nineteenth century authors used black humor in their horror stories. Author Robert Bloch called them "opposite sides of the same coin". 
In comedy horror film, gallows humor is a common element. While comedy horror films provide scares for audiences, they also provide something that dramatic horror films do not: "the permission to laugh at your fears, to whistle past the cinematic graveyard and feel secure in the knowledge that the monsters can't get you". 
In the era of silent film, the source material for early comedy horror films came from stage performances instead of literature. One example, The Ghost Breaker (1914), was based on a 1909 play, though the film's horror elements were more interesting to the audience than the comedy elements. In the United States following the trauma of World War I, film audiences sought to see horror on screen but tempered with humor. The "pioneering" comedy horror film was One Exciting Night (1922), written, directed and produced by D. W. Griffith, who noticed the stage success of the genre and foresaw a cinematic translation. While the film included comedic blackface performances, Griffith also included footage of a hurricane for a climactic storm. As an early experiment, the various genres were not well-balanced with horror and comedy, and later films improved the balance and took more sophisticated approaches.  Charles Bramesco of Vulture.com identifies Abbott and Costello Meet Frankenstein as the first commercially successful comedy horror film. Its success legitimized the genre and established it as commercially viable. 
Some comedy horror movies, such as the Scary Movie series or A Haunted House also function as parodies of popular horror films.

A comedy film is a category of film which emphasizes humor. These films are designed to make the audience laugh through the amusement. Films in this style traditionally have a happy ending. Comedy is one of the oldest genres in the film—and derived from the classical comedy in theatre. Some of the earliest silent films were comedies, as slapstick comedy often relies on visual depictions, such as sight gags and pratfalls, so they can be enjoyed without requiring sound. To provide drama and excitement to silent movies, live music was played in sync with the action on the screen, by pianos, organs, and other instruments. When sound films became more prevalent during the 1920s, comedy films grew in popularity, as laughter could result from both burlesque situations but now also from humorous dialogue.

A parody film or spoof film is a subgenre of comedy film that lampoons other film genres or films as pastiches, works created by imitation of the style of many different films reassembled together. Although the subgenre is often overlooked by critics, parody films are commonly profitable at the box office. Parody is related to satire, except that "parody is more often a representation of appreciation, while a satire is more often...pointing ...out the major flaws of an object through ridicule." J.M. Maher notes that the "difference is not always clear" and points out that "some films employ both techniques". Parody is found in a range of art and culture, including literature, music, theater, television, animation, and gaming.

American comedy films are comedy films produced in the United States. The genre is one of the oldest in American cinema; some of the first silent movies were comedies, as slapstick comedy often relies on visual depictions, without requiring sound. With the advent of sound in the late 1920s and 1930s, comedic dialogue rose in prominence in the work of film comedians such as W. C. Fields and the Marx Brothers. By the 1950s, the television industry had become serious competition for the movie industry. The 1960s saw an increasing number of broad, star-packed comedies. In the 1970s, black comedies were popular. Leading figures in the 1970s were Woody Allen and Mel Brooks. One of the major developments of the 1990s was the re-emergence of the romantic comedy film. Another development was the increasing use of "gross-out humour".
