The Guest is a 2014 American thriller film directed by Adam Wingard and written by Simon Barrett. The film stars Dan Stevens and Maika Monroe, with a supporting cast that includes Leland Orser, Sheila Kelley, Brendan Meyer, and Lance Reddick. It tells the story of a U.S. soldier (Stevens) called David who unexpectedly visits the Peterson family, introducing himself as a friend of their son who died in combat in Afghanistan. After he has been staying in their home for a couple of days, a series of deaths occur, and the daughter Anna (Monroe) suspects David is connected to them.

Barrett, who previously worked with Wingard on the films A Horrible Way to Die (2010) and You're Next (2011), wrote the script for The Guest. Budgeted at $5 million, filming took place in New Mexico during the summer of 2013. Musician Steve Moore scored the film's soundtrack. The film premiered at the Sundance Film Festival on January 17, 2014, and was theatrically released in the United States on September 17. The Guest received generally positive reviews from critics.
