Spencer's Mountain is an American family drama film written, directed, and produced in 1963 by Delmer Daves from a novel by Earl Hamner, Jr. The film stars Henry Fonda, Maureen O'Hara, and in early appearances in their careers, James MacArthur, Veronica Cartwright, and Victor French. Longtime Hollywood actor Donald Crisp plays "Grandpa", his final screen role.

The novel and film became the basis for the popular television series The Waltons, which followed in 1972. Differing from both the film and novel, The Waltons watered down many of the adult themes, including alcoholism and infidelity. Spencer's Mountain was the second of three films co-starring Henry Fonda and Maureen O'Hara. Twenty years earlier they starred in the 1943 war drama Immortal Sergeant and, ten years after Spencer's Mountain, played the leads in the 1973 made-for-television film adaptation of John Steinbeck's novel The Red Pony, directed and co-written by Spencer's Mountain second unit director Robert Totten.

Spencer's Mountain features the majestic scenery of Wyoming's Teton Range, as photographed by cinematographer Charles Lawton in Panavision and Technicolor. It was filmed in and around the town of Jackson and features the nearby Chapel of the Transfiguration. The novel and the series were set in the Virginia Appalachians, but Hamner said in 1963 that Daves wanted more imposing mountains to emphasize the characters' isolation and struggles with their environment.
