McArthur Peak, Mountain peak in Saint Elias Mountains, Canada

McArthur Peak is a mountain in the Saint Elias Mountains of Yukon that rises to approximately 4,344 meters. It stands as one of Canada's tallest summits and sits northeast of Mount Logan in a region covered by glaciers and snow.

The first successful climb of McArthur Peak occurred in 1961 when a team of five mountaineers ascended via the north ridge from Hubbard Glacier. This pioneering ascent demonstrated that the summit could be reached through demanding alpine techniques.

The peak honours James Joseph McArthur, a Dominion Land Surveyor who in 1887 made the first ascent of Mount Stephen, the first Canadian peak over 3,000 m to be climbed. The summit's name keeps his surveying work attached to the Saint Elias Mountains.

Visitors need advanced skills in glacier climbing, snow work, and ice climbing to reach this summit. Access comes through Kluane National Park and Reserve, which requires careful planning and preparation for the challenging approach.

A secondary summit two kilometres east of the main peak is called McArthur East. The main summit is Canada's 13th highest, and the first climbers reached it on 4 August 1961 from the Hubbard Glacier via the north ridge.
