Big 12 Logo

The Big 12 Conference is a group of 16 (originally 12) universities which compete in the NCAA Division I level. The conference was formed in 1994 but did not begin conference play until the fall of 1996. The schools that composed the Big 12 Conference in the most recent 2022–23 season, except West Virginia, were members of either the Big Eight Conference or the Southwest Conference, and have won six national titles including three titles since the inception of the Big 12 Conference.

The conference expanded to 16 members in the 2024–25 season with the return of charter-member Colorado, and the arrival of Arizona, Arizona State, and Utah.
