The 2011 Louisiana–Lafayette Ragin' Cajuns football program represented the University of Louisiana at Lafayette in the 2011 NCAA Division I FBS football season. The Ragin' Cajuns were led by first year head coach Mark Hudspeth and played their home games at Cajun Field. They are members of the Sun Belt Conference. They finished the season 9–4, 6–2 in Sun Belt play to finish in third place. They were invited to the New Orleans Bowl, the program's first ever bowl game, where they defeated San Diego State. However, in 2015 Louisiana–Lafayette vacated eight wins including their New Orleans Bowl victory due to alleged major NCAA violations.
