Northwest Passage, also billed as Northwest Passage , is a 1940 American Western film in Technicolor, directed by King Vidor. It stars Spencer Tracy, Robert Young, Walter Brennan and Ruth Hussey. The film is set in 1759, and tells a partly fictionalized version of the real-life St. Francis Raid by Rogers' Rangers, led by Robert Rogers on the primarily Abenaki village of St. Francis, in modern-day Canada. The screenplay, by Laurence Stallings and Talbot Jennings, is based on the 1937 historical novel Northwest Passage by Kenneth Roberts.

King Wallis Vidor was an American film director, film producer, and screenwriter whose 67-year film-making career successfully spanned the silent and sound eras. His works are distinguished by a vivid, humane, and sympathetic depiction of contemporary social issues. Considered an auteur director, Vidor approached multiple genres and allowed the subject matter to determine the style, often pressing the limits of film-making conventions.
