Pete Mathews Coliseum is a 3,500-seat multi-purpose arena in Jacksonville, Alabama. It is home to the Jacksonville State University Gamecocks men's and women's basketball teams as well as the women's volleyball team. It also hosts the annual Calhoun County High School Basketball Tournament held each January, in which all high school basketball teams in Calhoun County, Alabama compete. The arena has been the annual host for this event since the early 1990s. Prior to that time, the event was held in different facilities around Calhoun County. The venue opened in 1974 when the basketball team moved there from Stephenson Hall. In addition to the arena, the coliseum also houses an indoor swimming pool. Prior to the 2015 renovation, a concourse that was used as a jogging track circled the basketball court.
