The Provence Alps and Prealps (Alpes et Préalpes de Provence in French) are a mountain range in the south-western part of the Alps, located in Provence-Alpes-Côte d'Azur (France). Provence Alps and Prealps encompass the south-western area of the French Prealps.
The western slopes of the range are drained by the Rhone river through the Durance and other tributaries while its south-eastern part is drained by the Var and several smaller rivers that flow directly to the Mediterranean Sea.
