# Colorado–Kansas State football rivalry

The Colorado–Kansas State football rivalry is an American college football rivalry between the University of Colorado Buffaloes and Kansas State University Wildcats. The rivalry dates from their first college football game in 1912, and has continued across all sports, including basketball since their time in the Big Eight Conference joining in 1947. The rivalry intensified while the two schools were conference foes and members of the Big 12 Conference from 1996 to 2010. The rivalry was renewed in 2016 and was slated for a home-and-home series in 2027 and 2028. On July 1, 2024, Colorado rejoined the Big 12, rekindling the rivalry. The teams will meet at Folsom on Oct 12, 2024.

## Series history

Colorado leads the series 45–21–1. As former Big 8 and Big 12 rivals, the teams played annually against each other in all sports from 1948 to 2010.
In 2016, Colorado football announced a renewed rivalry series between Kansas State in a home-and-home series in 2027 and 2028. Following Colorado's announcement that it would rejoin the Big 12 starting in 2024, the two will likely play as regular conference opponents, earlier than the series that was previously scheduled. On November 1, 2023, the Big 12 announced the opponents for the 2024 through 2027 seasons, with Colorado and Kansas State scheduled to meet in 2024, 2025, and 2026.
