Aliens vs. Predator: Requiem (stylized on-screen as AVPR: Aliens vs Predator - Requiem) is a 2007 American science fiction horror action film starring Steven Pasquale, Reiko Aylesworth, John Ortiz, Johnny Lewis and Ariel Gade. The directorial debut of The Brothers Strause, the film was written by Shane Salerno and is a direct sequel to Alien vs. Predator (2004) as well as the second and latest installment in the Alien vs. Predator franchise, the sixth film in the Alien franchise and the fourth film in the 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 "cleaner" 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. The film received generally negative reviews from critics for its poor lighting, editing, and lack of originality. It grossed $130.2 million worldwide against a production budget of $40 million. Plans for another sequel were abandoned, with further independent entries in both franchises released in 2010 and 2012 respectively.
