O' Horten is a 2007 internationally co-produced comedy-drama film written and directed by Bent Hamer. The film's title character Odd Horten is a habit-bound train driver, who is about to retire. On the day of his retirement he ends up in an unexpected situation, and is forced to reconsider his life. As in other films by Hamer, the themes are loneliness and old age, and the courage to take chances. O' Horten has been described as a film without a strong plot or a clear chronology.

The film's main cast consists mainly of senior Danish and Norwegian actors, including Bård Owe, Espen Skjønberg, and Ghita Nørby. There are also several cameos from various well-known Norwegians, such as ski jumper Anette Sagen in her first film role. The music was composed by John Erik Kaada. Generally well received by critics, it was chosen for Un Certain Regard at the Cannes Film Festival. Skjønberg was awarded an Amanda Award for Best Actor in a Supporting Role.
