The Chartreuse Mountains is a mountain range in southeastern France, stretching from the city of Grenoble south to the Lac du Bourget north. It is the southernmost range in the Jura Mountains and belongs to the French Prealps.
One of the larger cities in the Chartreuse Mountains is Voiron (Isère).
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, named after the drink.
