Lord of Illusions is a 1995 American neo-noir supernatural horror film written and directed by Clive Barker, based on his own short story The Last Illusion published in 1985 in the anthology Books of Blood Volume 6. The same story introduced Barker's occult detective Harry D'Amour, who later appeared in several prose stories and comic books. Lord of Illusions is D'Amour's first onscreen appearance, with the character portrayed by actor Scott Bakula. Other actors appearing in the film include Kevin J. O'Connor, Famke Janssen and Daniel von Bargen. The story features D'Amour, who has had several experiences with the supernatural, embarking on an investigation involving a stage illusionist named Swann and a cult led by a sorcerer named Nix.

Although Clive Barker decided to keep a few story elements and the same principal characters from "The Last Illusion", he otherwise presented a new story for the movie and created a new villain, surprising several readers familiar with the original work. The film met with mixed reception and no further live-action movies featuring Harry D'Amour were made.
