Mount Hubbard, Mountain peak in Saint Elias Range, Canada and Alaska.

Mount Hubbard is a 4,557 m summit of the Saint Elias Range on the Alaska–Yukon border, within Wrangell–St. Elias National Park and Kluane National Park and Reserve. It is the highest point of a massif that also holds Mount Alverstone and Mount Kennedy, with the Hubbard Glacier to the west and the Lowell Glacier on its east flank.

The mountain was named in 1890 by geologist Israel Russell after Gardiner Greene Hubbard, the founding president of National Geographic Society. This naming reflects the peak's importance during the era of North American geographical exploration.

The name honours Gardiner Greene Hubbard, first president of the National Geographic Society, which co-funded Israel Russell's 1890 expedition; Russell, a USGS geologist, chose it that year. The peak also anchors a border corner: from Hubbard and Mount Alverstone the Canada–United States line runs west toward Mount Saint Elias and south toward the Alaska panhandle.

Climbers typically plan expeditions during the warmer months from spring through autumn, when snow and ice present fewer obstacles. Access is available from both the Canadian and American sides, with route selection depending on seasonal conditions.

The first ascent was made on 26 July 1951 by Walter Wood, Peter Wood, Robert Bates and Nicholas Clifford. The peak rises 2,300 m above the Alverstone Glacier in under 3.2 km, and 3,350 m above the Hubbard Glacier in 11.3 km, one of the largest local reliefs of any North American summit.
