Opelousas is the parish seat of St. Landry Parish, Louisiana, and is one of the former capitals of Louisiana. Opelousas is in the south Louisiana area known as "Acadiana", the center of Cajun culture in Louisiana. Opelousas is also on the far eastern edge of the geographic region known as the "Cajun Prairie." This is due to the extensive prairie lands that extend from northeast of Lake Charles eastward to the edge of Opelousas.
