Alien Love Triangle is a 2008 comedy-science fiction short film directed by Danny Boyle and written by John Hodge. 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 canceled.

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. After this, there were 2 other recorded screenings of this film. The first at the National Media Museum shortly after the premiere, again with Branagh in attendance, and the second in 28 October 2023 at the FilmBath Festival, with Danny Boyle and John Hodge in attendance.
