Saintes-Maries-de-la-Mer, is the capital of the Camargue in the south of France. It is a commune in the Bouches-du-Rhône department by the Mediterranean Sea. It covers the second-largest area of all communes in Metropolitan France, smaller only than that of neighbouring Arles.

The Camargue is a coastal region in southern France located south of the city of Arles, between the Mediterranean Sea and the two arms of the Rhône river delta. The eastern arm is called the Grand Rhône; the western is the Petit Rhône. It constitutes western Europe's largest river delta.
