Testament is a 1983 drama film based on a three-page story titled "The Last Testament" by Carol Amen (1933–1987), directed by Lynne Littman and written by John Sacret Young. The film tells the story of how one small suburban town near the San Francisco Bay Area slowly falls apart after a nuclear war destroys outside civilization. It was one of the films, along with The Day After and Threads that portrayed life after a nuclear war, mostly in response to an increase in hostility between the United States and the Soviet Union.

John Sacret Young was an American author, producer, director, and screenwriter primarily in television, perhaps best known for his work on the show China Beach. Young was nominated for seven Emmys and seven Writers Guild of America Awards, winning two WGA Awards.
