The Decatur campus serves as home for the Warhawks athletic teams. Both baseball fields, and the Carlton Kelly Gymnasium, are housed on the campus. Calhoun participates in
baseball and
softball in the
Alabama Community College Conference. Due to the small size of both
Decatur and
Austin High School's gymnasiums, the rivalry basketball game is held each year at the 3,000-seat Carlton Kelly Gymnasium to accommodate the large crowds. However, this gym is still not the correct size for the event as crowds up to 4,000 in size attempt to attend the event and upwards of 1,000 can be turned away at each rivalry game. ==Notable alumni==
