The Colorado Buffaloes are the athletic teams that represent the University of Colorado. The university sponsors 17 varsity sports teams. Both the men's and women's teams are called the Buffaloes (Buffs for short) or, rarely, the Golden Buffaloes. "Lady Buffs" referred to the women's teams beginning in the 1970s, but was officially dropped in 1993. The nickname was selected by the campus newspaper in a contest with a $5 prize in 1934 won by Andrew Dickson of Boulder. The university participates as a member of the Pac-12 Conference at the National Collegiate Athletic Association (NCAA) Division I Football Bowl Subdivision (FBS) level. Rick George was announced as the sixth athletic director in program history on July 17, 2013, following the resignation of Mike Bohn, and after an interim appointment by former Women's Basketball Head Coach former deputy Athletic Director Ceal Barry.

A bison calf was rented from a local ranch and ran along the sidelines. The year 1947 marked key point in race relations on campus. The Buffaloes joined the Missouri Valley Intercollegiate Athletic Association, commonly known as the Big Six.
