The Chartreuse Mountains (French: Massif de la Chartreuse [masif d(ə) la ʃaʁtʁøz]) are a mountain range in southeastern France, stretching from the city of Grenoble in the south to the Lac du Bourget in the north. They are part of the French Prealps, which continue as the Bauges to the north and the Vercors to the south.

The name Chartreuse is derived from the village now known as Saint-Pierre-de-Chartreuse, earlier Catorissium, Cantourisa, Caturissium, and Chatrousse. It appears to be of Gaulish origin; and is perhaps related to the name of the Caturiges tribe.

The mountain range rises between Grenoble (south), Chambéry (north), Voiron and Saint-Laurent-du-Pont (west) and Grésivaudan (Isère valley, east)

The Chartreuse Mountains gave their name to the monastery of the Grande Chartreuse, the monastic Carthusian Order takes its name from these mountains, where its first hermitage was founded in 1084. Also derived from the mountain range's name is that of the alcoholic cordial Chartreuse produced by the monks since the 1740s, and of the chartreuse colour, greenish hue of the Chartreuse liqueur, named after the drink.
