The overall Chattanooga FC fan base is known as 'The Chattahooligans,' with the official supporter group also going by that name. Over the years, the supporter group has established several traditions, which the club has incorporated into home match proceedings such as a pre-game Chattahooligan march-in and the a capela leading of the National Anthem.
