London Voodoo is a 2004 British horror film written, produced, and directed by Robert Pratten; and starring Doug Cockle, and Sara Stewart.

When ambitious analyst Lincoln Mathers (played by Doug Cockle) relocates his family from New York to London, his wife Sarah (Sara Stewart) discovers a new disturbing power and becomes hostage to an ancient spirit.

As Mathers notices that the family is tearing apart and that his wife's behavior becomes more violent and erratic, he accepts that to save the woman he married he must take a leap of faith.

London Voodoo was released on DVD by Heretic Films on 31 May 2005.

Dennis Harvey from Variety gave the film a mixed review, writing, "Maintaining a straight face even as the action takes a turn toward the ludicrous, English horror entry London Voodoo should please genre fans, though it lacks the originality or name thesps that might’ve merited theatrical pickup.
