The 1971 Nebraska vs. Oklahoma football game was the 51st edition of the rivalry, one of several labeled as a "Game of the Century." The Big Eight Conference matchup was held on Thursday, November 25, 1971, in Norman, Oklahoma.

The top-ranked Nebraska Cornhuskers, defending national champions with a 20-game winning streak (and 29 without a loss), traveled south to play the second-ranked Oklahoma Sooners. In a game that lived up to the hype, the Cornhuskers scored a late touchdown to defeat the Sooners by four, 35–31.

The teams combined for 17 of 22 first-team All-Big Eight players. Nebraska had the nation’s top-ranked defense. Oklahoma had the nation's most productive offense with their wishbone averaging over 472 rushing yards per game, a NCAA record.

The cover of Sports Illustrated (November 22) prior to the game included photographs of Nebraska linebacker Bob Terrio and Oklahoma running back Greg Pruitt, nose-to-nose, beneath the headline: "Irresistible Oklahoma Meets Immovable Nebraska." Both teams had twelve days to prepare, as neither had played on the preceding Saturday.

The Husker "Blackshirts" defense included seven first-team All-Big Eight selections, four players who would earn consensus All-America recognition during their careers and two Outland Trophy winners: tackle Larry Jacobson and middle guard Rich Glover. Glover would win both the Outland and Lombardi awards in 1972 and eventually be inducted into the College Football Hall of Fame. They were joined in the starting lineup by end Willie Harper, like Glover, a two-time All-American. John Dutton, an All-American in 1973, was a sophomore backup.
