The Dauphiné Prealps ( French: Préalpes du Dauphiné) are a mountain range in the south-western part of the Alps. They are located in Rhône-Alpes and, marginally, in Provence-Alpes-Côte d'Azur (south-eastern France). Dauphiné Prealps are the central section of the French Prealps.

Administratively the French part of the range belongs to the French departments of Isère, Drôme, Hautes-Alpes and, marginally, Alpes-de-Haute-Provence. The whole range is drained by the Rhône river.
SOIUSA classification
According to SOIUSA (International Standardized Mountain Subdivision of the Alps) the mountain range is an Alpine section, classified in the following way: [3]
- Main part = Western Alps
- Major sector = South Western Alps
- Section = Dauphiné Prealps
- Code = I/A-6
Borders
Dauphiné Prealps' borders are (anticlockwise):
- Isère (north);

- Buëch, Col de Macuègne - which connects them with Provence Alps and prealps - and Toulourenc river (south);
- Rhone and Isère valleys (west).
