2021 Louisiana Ragin' Cajuns football team

The 2021 Louisiana Ragin' Cajuns football team represented the University of Louisiana at Lafayette in the 2021 NCAA Division I FBS football season. The Ragin' Cajuns played their home games at Cajun Field in Lafayette, Louisiana, and compete in the West Division of the Sun Belt Conference. They were led by fourth-year head coach Billy Napier. The Cajuns began the season with an away matchup against Big 12's Texas and concluded their regular season at conference and in-state rival Louisiana–Monroe.

Napier was named the head coach of the Florida Gators on November 28. He announced that he would coach in the Sun Belt Championship Game on December 4 before departing. Napier led the Ragin’ Cajuns to their first outright Sun Belt championship win, defeating the Appalachian State Mountaineers, and left the Ragin’ Cajuns on a victorious note. On December 5, the same date as Napier's departure, Louisiana announced that then-offensive coordinator Michael Desormeaux would be promoted to head coach for the team's bowl game and the 2022 season. In his first game, Desormeaux defeated Marshall in the 2021 New Orleans Bowl.
