The Cajuns (/ˈkeɪdʒənz/; French: les Cadjins [le kadʒɛ̃] or les Cadiens [le kadjɛ̃]), also known as Louisiana Acadians (French: les Acadiens), are an American ethnic group mainly found in the US state of Louisiana and the surrounding Gulf Coast states.
While Cajuns are usually described as the descendants of the Acadian exiles who went to Louisiana over the course of Le Grand Dérangement, Louisianians frequently use Cajun as a broad cultural term (particularly when referencing Acadiana) without necessitating race or descent from the deported Acadians. Although the terms Cajun and Creole today are often portrayed as separate identities, Louisianians of Acadian descent have historically been known as, and are, a subset of Creoles (synonymous for "Louisianais", which is a demonym for French Louisianians). Cajuns make up a significant portion of south Louisiana's population and have had an enormous impact on the state's culture.
