OU Credit Union O'rena

The OU Credit Union O'rena is the home of Oakland Golden Grizzlies men's and women's basketball in Rochester, Michigan. The arena serves as the centerpiece of Oakland University athletics and also hosts volleyball. Its dark, distinctive playing surface gives the building an identity all its own among Horizon League venues.

Opened November 17, 1998 as Oakland moved up to Division I, the arena is known for its all-black court, nicknamed 'The Blacktop' since the 2015-16 season. It carried the name Athletics Center O'rena before a 2023 naming-rights deal with Oakland University Credit Union. It has hosted Oakland's Horizon League teams, including multiple NCAA Tournament squads built by longtime coach Greg Kampe.
