Out of the Blue (released in Canada as No Looking Back) is a 1980 drama film directed by Dennis Hopper, and starring Linda Manz, Hopper, Sharon Farrell, Don Gordon, and Raymond Burr. The film was produced by Leonard Yakir and written by him and Brenda Nielson. Its plot follows a troubled and rebellious teenage girl living in the Pacific Northwest with her dysfunctional mother and alcoholic father. The title is taken from the Neil Young song "My My, Hey Hey (Out of the Blue)", which is also featured in the film.

The film competed for the Palme d'Or at the 1980 Cannes Film Festival, where it was met by controversy for its frank depiction of juvenile delinquency, drug use, and incest.
