A calanque is a steep-sided valley formed within karstic regions either by fluvial erosion or the collapse of the roof of a cave that has been subsequently partially submerged by a rise in sea level.

== Characteristics == ===Location=== The best known examples of this formation can be found in the Massif des Calanques (Massís dei calancas in Occitan, the traditional local language) in the Bouches-du-Rhône department of Southern France. The range extends for in length and in width along the coast between Marseille and Cassis, culminating in Mont Puget (). Similar calanques can also be found on the French Riviera near the Massif de l'Esterel and on the island of Corsica (Calanques de Piana). The highest points along the calanques are located at Mont Puget () and in the mountains of Marseilleveyre (). Similarities are seen between calanques and rias, the river mouths formed along the coast of Brittany in Northern France.
