In the Bedroom is a 2001 American drama film directed by Todd Field from a screenplay written by Field and Robert Festinger, based on the 1979 short story "Killings" by Andre Dubus. It stars Sissy Spacek, Tom Wilkinson, Nick Stahl, Marisa Tomei, and William Mapother. The film centers on the inner dynamics of a family in transition. Matt Fowler (Wilkinson) is a doctor practicing in Maine and is married to Ruth Fowler (Spacek), a music teacher. Their son Frank (Stahl) is involved in a love affair with an older single mother, Natalie Strout (Tomei). As the beauty of Maine's brief and fleeting summer comes to an end, these characters find themselves in the midst of an unimaginable tragedy.

The title refers to the rear compartment of a lobster trap known as the "bedroom" and how it can hold only two lobsters before the lobsters begin to turn on each other. In the Bedroom premiered at the Sundance Film Festival. It was theatrically released in limited theatres on November 23, 2001, and grossed $44.8 million against a $1.7 million budget.

In the Bedroom was chosen by the American Film Institute as one of the top ten films of the year while Spacek's performance was named the best female performance of the year. The film received five Oscar nominations at the 74th Academy Awards: Best Picture, Best Actress (for Spacek), Best Actor (for Wilkinson), Best Supporting Actress (for Tomei), and Best Adapted Screenplay, and also three nominations at the 59th Golden Globe Awards including for the Best Motion Picture – Drama, and winning Best Actress – Drama (for Spacek).
