Boogeyman is a 2005 supernatural horror film directed by Stephen Kay and starring Barry Watson, Emily Deschanel, Skye McCole Bartusiak, Tory Mussett, Charles Mesure, and Lucy Lawless. Written by Eric Kripke, Juliet Snowden, and Stiles White, from a story by Kripke, the film is a new take on the classic "boogeyman", or monster in the closet, who is the eponymous antagonist of the film. The plot concerns a young man, Tim Jensen, who must confront the childhood terror that has affected his life.

The film was nearly panned by critics, often citing a generic and unoriginal plot as the main criticism. Despite receiving negative reviews from critics, it was a financial success and was followed by two direct-to-video sequels, Boogeyman 2 (2007) and Boogeyman 3 (2008).
