The Laurentian Mountains (French: Laurentides) are a mountain range in southern Quebec, Canada, north of the St. Lawrence River and Ottawa River, rising to a highest point of 1,166 m (3,825 ft) at Mont Raoul Blanchard, north east of Quebec City in the Réserve Faunique des Laurentides. The Gatineau, L'Assomption, Lièvre, Montmorency, Nord and St. Maurice rivers are sourced from lakes in this mountain range.

As a part of the Canadian (Precambrian) Shield, the Laurentians are a part of the same geologic formation as the Adirondack Mountains in New York State, although the Adirondacks are sometimes included with the Appalachian Mountains.

Note that although one of Quebec's official regions is called Laurentides, the mountain range runs through four other regions; Capitale-Nationale, Outaouais, Lanaudière, and Mauricie. The foothills of the Laurentian range extend into Northeastern Ontario, particularly towards Bonnechere, Ontario as the Laurentian Highlands, Madawaska Highlands, a range of hills near the Madawaska River and Opeongo Lake, and the Opeongo Hills (another range of high hills, near Round Lake) in Ontario near the town of Combermere.

The Laurentian Mountain range is one of the oldest mountain ranges in the world. It contains rocks deposited during Cambrian time, 540 million years ago. ^[1]. The Laurentians are the central part of the Grenville orogeny 1100-1000 mya (million years) ago.

Scenes from the 1996 film Snowboard Academy were shot here.
