The Savoy Prealps (French: Préalpes de Savoie ) are a mountain range in the north-western part of the Alps . They are located in Rhône-Alpes (south-eastern France) and, marginally, in Valais (western Switzerland). Savoy Prealps encompass northernmost area of the French Prealps.

Administratively the French part of the range belongs to the French departments of Savoie, Haute Savoie and Isère while the Swiss one is divided between the districts of Saint-Maurice and Monthey. The whole range is drained by the Rhone river.
