The Camargue (Occitan: Camarga in classical norm or Camargo in Mistralian norm) is a natural region located south of Arles, France, between the Mediterranean Sea and the two arms of the Rhône River delta. The eastern arm is called the Grand Rhône; the western one is the Petit Rhône.
Administratively it lies within the département of Bouches-du-Rhône, the appropriately named "Mouths of the Rhône", and covers parts of the territory of the communes of Arles – the largest commune in Metropolitan France, Saintes-Maries-de-la-Mer – the second largest – and Port-Saint-Louis-du-Rhône. A further expanse of marshy plain, the Petite Camargue (little Camargue), just to the west of the Petit Rhône, is in the département of Gard.
Camargue was designated a Ramsar site as a "Wetland of International Importance" on 1 December 1986.
