Louisiana's Ragin' Cajuns is the trademarked nickname of the athletic teams of The University of Louisiana at Lafayette UL Lafayette, that was earlier known as the University of Southwestern Louisiana and was the first team to adopt the nickname Ragin' Cajuns, to refer to its football team.

Prior to the 1960s, the team's nickname was the "Bulldogs." Until the 2006-07 academic year, the women's teams were referred to as the Lady Cajuns, but they now use the same "Ragin' Cajuns" nickname as the men's teams.

Football was the first sports team organized at the then Institute (SLII) in the year 1901, although an advertisement promoting women's gymnastics was placed in the year 1900. Louisiana's Ragin' Cajun alumni have had notable professional sports careers in the NFL, NBA, MLB and as Olympic medalists.
