The Cajundome is a 12,068 seat multi-purpose arena in Lafayette, Louisiana. It is home to the Louisiana's Ragin' Cajuns basketball teams of the University of Louisiana at Lafayette, Lafayette Wildcatters of the Southern Indoor Football League and the Louisiana high school basketball state championship.

The arena also hosts many regional concerts (seating for concerts 8,481 to 13,500) and special events, such as World Wrestling Entertainment (WWE) events and the annual outdoor Cajun Heartland State Fair, an eleven day state fair that attracts over 175,000. The facility is a recognizable landmark of the city of Lafayette that is managed by the Cajundome Commission.

From the mid 1990s through the mid 2000s it was home to the ECHL's now-defunct Louisiana IceGators. During that time, the arena earned the nickname 'The Frozen Swamp'. In 2010 it became official that the Louisiana IceGators, now as part of the SPHL, would make a return to 'The Frozen Swamp'. It also hosted the 1998, 1999, and 2007 Sun Belt Conference men’s basketball tournaments.
