McKenzie Arena is the primary basketball arena for the University of Tennessee at Chattanooga (UTC) in Chattanooga in the U.S. state of Tennessee. It replaced Maclellan Gymnasium, a 4,177-seat gymnasium now used for women's volleyball and wrestling. Originally called UTC Arena, it was renamed McKenzie Arena on February 21, 2000, in honor of athletic supporters Toby and Brenda McKenzie of Cleveland, Tennessee. The arena opened on October 8, 1982. It was designed by Campbell & Associates Architects with David J. Moore as the on-site architect/construction administrator.
