Blue Sky is a 1994 American drama film directed by Tony Richardson and starring Jessica Lange, Tommy Lee Jones, Powers Boothe, Carrie Snodgress, Amy Locane, and Chris O'Donnell. It tells the story of a nuclear coverup. It was adapted by Rama Stagner, Arlene Sarner and Jerry Leichtling. The original music score was composed by Jack Nitzsche.

Filmed from May 14 to July 16, 1990, the film was completed in 1991, but because of the bankruptcy of Orion Pictures, it sat on the shelf until 1994, three years after Richardson's death on November 14, 1991, making this his final film. The film won critical praise and Lange won the 1994 Academy Award for Best Actress, along with the Golden Globe Award and the Los Angeles Film Critics Association award.

The film is based on Rama Stagner-Blum's real life and the relationship between her parents, Clyde and Gloria Lee Moore-Stagner, during the 1960s while her father was in the army. They later divorced and Gloria remarried before dying in 1982.
