Room is a 2015 internationally co-produced survival psychological drama film directed by Lenny Abrahamson and written by Emma Donoghue, based on her 2010 novel.

The film was a co-production of Canada, Ireland, the United Kingdom, and the United States and was shot in Toronto, with the set built at Pinewood Toronto Studios.
