File:Flag of Acadiana.svg

In 1965, Thomas J. Arceneaux of Lafayette Louisiana, former dean of Agriculture at the University of Southwestern Louisiana designed the Louisiana Acadian flag. A description of this flag follows:

To symbolize the French heritage and origin of the Acadians there are three silver fleur-des-lis on a blue background. To symbolize Spain, who governed Louisiana for 40 years and was in possession of the Louisiana territory when the Acadians arrived, the old arms of the Castille, a gold tower on a red field. The gold star on a white field represents “Our Lady of the Assumption”, Patroness of the Acadians. The star also symbolizes the active participation of the Acadians in the American Revolution, as soldiers under Galvez.

(Don Landry, 7 October 1997, crwflags.com) It was adopted in 1965 by the Comité acadien and in 1972 by the Louisiana state.
