Mount Slaggard, Mountain summit in Kluane National Park, Canada.

Mount Slaggard is a mountain summit in the Saint Elias range located within Kluane National Park, rising to approximately 4,740 meters. The peak features glacial terrain and permanent snowfields that dominate its upper slopes and surrounding valleys.

On 11 August 1959, Barbara Lilley, Bud Bingham, Jon Shinno, Sy Ossofsky, Ray D'Arcy, George Wallerstein, Fred Martin and Bill Davis made the first ascent, climbing the east ridge. The 4,742-metre peak lies in the northern part of Kluane National Park, surrounded by higher summits such as Mount Wood, 7.74 km to the north-northeast.

Mount Slaggard lies in the northern part of Kluane National Park and Reserve, in Canada's Yukon. The park is a UNESCO World Heritage Site, and the mountain's name is shared with the wider Saint Elias range that surrounds it. Its northwest flank drains toward the Anderson Glacier, while the southeast side feeds the Chitina Glacier system.

Climbing this peak requires specialized mountaineering gear, glacier experience, and thorough physical preparation. The warmer months offer more stable conditions than winter, though weather can change rapidly throughout the year.

Mount Slaggard is the tenth highest peak in Canada, and its first ascent on 11 August 1959 went up the east ridge, by Barbara Lilley, Bud Bingham, Jon Shinno, Sy Ossofsky, Ray D'Arcy, George Wallerstein, Fred Martin and Bill Davis.
