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 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 building is an eight-sided concrete structure, with three levels: arena floor, service level, and the concourse level.

The approximate elevation at street level is above sea level making it the college basketball arena with the 5th highest elevation in the country.

In April 2008, the men's and women's basketball offices were relocated to the CEC from Folsom Field second level where the conference rooms were previously located.
