Alien Love Triangle is a 2008 comedy-science fiction short film directed by Danny Boyle. It was filmed in 1999.

The film was originally intended to be one of a trilogy of 30-minute short films shown together. However, the two other films, Mimic and Impostor, were turned into full-length features, and the project was cancelled.The film had its world premiere as part of the closing ceremony of the smallest theatre in the UK, La Charrette, on 23 February 2008, an event organised by Mark Kermode of The Culture Show. Kenneth Branagh attended the screening. The film's only other recorded screening was shortly after the premiere, at the Kenneth Branagh season at the National Media Museum, again with Branagh in attendance.
