The CU Events Center is an 11,064-seat multi-purpose arena in the western United States, on the main campus of the University of Colorado in Boulder, Colorado. Opened 44 years ago in 1979, it is home to the Colorado Buffaloes men's and women's basketball teams and women's volleyball of the Pac-12 Conference. The playing surface is named the Sox Walseth Court in honor of the former Buffaloes men's and women's basketball head coach.

The Colorado Buffaloes are the athletic teams that represent the University of Colorado Boulder. The university sponsors 16 varsity sports teams. Both the men's and women's teams are called the Buffaloes 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.
