Lake Borgne (French: Lac Borgne, Spanish: Lago Borgne) is a lagoon of the Gulf of Mexico in southeastern Louisiana. Although early maps show it as a lake surrounded by land, coastal erosion has made it an arm of the Gulf of Mexico. Its name comes from the French word borgne, which means "one-eyed."
