Catahoula Island is the name I gave to the long land mass in St. Martin Parish, Louisiana that lies to the north and west of the village of Catahoula.
Most of the finger-shaped island, except for a hamlet at the southernmost knuckle, is uninhabited. The Catahoula Levee Road and the channel beside it wind their way along the eastern edge of the island. The western edge of the island is a channel connecting Allemond Point, the northernmost tip of the island, with the village of Catahoula and Catahoula Lake at the southernmost tip of the island.
