The Cajundome is a 13,500 seat multi-purpose arena located in Lafayette, Louisiana. It is home to the Louisiana–Lafayette Ragin' Cajuns men's basketball program, often referred to by the nickname Louisiana or Louisiana Ragin' Cajuns(as well as the Ragin' Cajuns women's basketball program when the men and women play doubleheaders), 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 Lafayette landmark that was built by the State of Louisiana, funded by the City of Lafayette, and is owned by the University of Louisiana at Lafayette and 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'. The Cajundome has been home to the Lafayette SwampCats of the EISL and the Lafayette Roughnecks of the af2. It also hosted the 1998, 1999, and 2007 Sun Belt Conference men’s basketball tournaments. The arena also hosts the annual Beta Club Louisiana state conventions.
