The Red River Rivalry, commonly known as the OU-Texas Game or the Texas-OU Game, is the name for the annual college football game between the University of Texas Longhorns and the University of Oklahoma Sooners. The series is considered one of the greatest rivalries in American sports. Both schools consider the game to be one of their biggest rivalries, alongside their in-state rivalries with the Texas Aggies, for the Longhorns, and the Oklahoma State Cowboys, for the Sooners. The name is derived from the Red River that forms part of the boundary between the U.S. states of Texas and Oklahoma. The game originated in 1900, while Oklahoma was still a United States territory and the Oklahoma campus was still in Oklahoma Territory.
