Aliens vs. Predator: Requiem (stylized as AVPR: Aliens vs Predator - Requiem) is a 2007 American science fiction action film directed by the Brothers Strause (Colin and Greg Strause) in their directorial debut and written by Shane Salerno. The film stars Steven Pasquale, Reiko Aylesworth, John Ortiz, Johnny Lewis and Ariel Gade.

It is a sequel to Alien vs. Predator (2004), and the second and latest installment in the Alien vs. Predator franchise, continuing the crossover between the Alien and Predator franchises. Set immediately after the events of the previous film, the film begins with a Predator ship crashing into a forest outside of Gunnison, Colorado, where an Alien-Predator hybrid known as the Predalien escapes and makes its way to the nearby small town. A skilled veteran Predator is dispatched to kill the Predalien, and the townspeople try to escape the ensuing carnage.

Aliens vs. Predator: Requiem premiered on November 4, 2007 in Los Angeles. It was released theatrically on December 25 in the United States. It received generally negative reviews, with criticism for its poor lighting, editing, and plot. It grossed $130.2 million worldwide against a production budget of $40 million, and plans for a further sequel were put on hold indefinitely.
