Mount Cartier is a 2,610-metre (8,563-foot) mountain summit located in British Columbia, Canada.

[6] Mount Cartier is part of the Duncan Ranges which is a subrange of the Selkirk Mountains.

[1] Precipitation runoff from the mountain drains west to Arrow Lakes which is a reservoir of the Columbia River.

Mount Cartier is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising 2,174 meters (7,133 ft) above Upper Arrow Lake in 5 km (3.1 mi).

He was born at Antoine, Quebec; served as attorney general for Lower Canada (1856); and as joint Prime Minister with Sir John A. Macdonald.
