Knute Rockne, All American is a 1940 American biographical film that tells the story of Knute Rockne, Notre Dame's legendary football coach. It stars Pat O'Brien as Rockne and Ronald Reagan as player George Gipp, as well as Gale Page, Donald Crisp, Albert Bassermann, Owen Davis Jr., Nick Lukats, Kane Richmond, William Marshall and William Byrne. The film also includes cameos by football coaches "Pop" Warner, Amos Alonzo Stagg, William H. Spaulding and Howard Jones, playing themselves.

Reagan's presidential campaign revived interest in the film, and as a result, some reporters called him the Gipper.

The movie was written by Robert Buckner and directed by Lloyd Bacon, who replaced William K. Howard after filming had begun. In 1997, the film was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress and selected for preservation in the National Film Registry.
