Mont Jacques-Cartier, Mountain summit in Gaspesian Provincial Park, Canada.

Mont Jacques-Cartier is the highest peak of the Chic-Choc Mountains in eastern Quebec, reaching 1,268 m and forming the roof of the Canadian Appalachians. Its summit plateau lies above the treeline and shows alpine tundra vegetation and periglacial features such as sorted polygons and block fields. The mountain stands within Gaspésie National Park.

In 1923 American botanists and the Quebec botanist Brother Marie-Victorin studied the summit flora, and the peak was then called Botanist's Dome. In 1934 the Geographic Board of Canada proposed the name Jacques Cartier for the 400th anniversary of his first voyage to Canada. From 1942 the Canadian military ran an aerial observation base on the mountain until the end of World War II.

The summit was long called Botanist's Dome, or pic des Botanistes, after the American botanists and the Quebec botanist Brother Marie-Victorin who studied its flora there in 1923. In 1934 the Canadian Geographic Board chose the name Jacques Cartier for the 400th anniversary of his first voyage to Canada.

The hiking trails are most accessible between June and September when weather is stable and paths are well maintained. Visitors should bring warm clothing since temperatures at the summit are significantly cooler than in lower valleys.

The summit area is a final refuge for woodland caribou populations south of the Saint Lawrence River, representing one of the last remaining groups. These rare animals are difficult to spot, yet their presence makes this location a crucial sanctuary for the species.
