The Blair Witch Project is a 1999 American supernatural horror film written, directed and edited by Daniel Myrick and Eduardo Sánchez. It is a fictional story of three student filmmakers—Heather Donahue, Michael C. Williams, and Joshua Leonard—who hike into the Black Hills near Burkittsville, Maryland, in 1994 to film a documentary about a local myth known as the Blair Witch. The three disappear, but their equipment and footage are discovered a year later. The purportedly "found footage" is the movie the viewer sees.

Supernatural horror film is a film genre that combines aspects of supernatural film and horror film. Supernatural occurrences in such films often include ghosts and demons, and many supernatural horror films have elements of religion. Common themes in the genre are the afterlife, the Devil, and demonic possession. Not all supernatural horror films focus on religion, and they can have "more vivid and gruesome violence".
