Administrative division in Provence-Alpes-Côte d'Azur, France
Cassis (French pronunciation: [kasi]; Occitan: Cassís) is a commune situated east of Marseille in the department of Bouches-du-Rhône in the Provence-Alpes-Côte d'Azur region, whose coastline is known in English as the French Riviera, in Southern France. It is a popular tourist destination, famous for its cliffs (falaises) and the sheltered inlets called calanques.
