Mount Unwin, Mountain summit in Jasper National Park, Canada

Mount Unwin is a 3,268-metre summit on the west side of Maligne Lake in the Queen Elizabeth Range of the Canadian Rockies, within Jasper National Park, Alberta. Its nearest higher peak is Mount Brazeau, 13.0 km to the east-southeast. The mountain rises 818 metres above its surroundings.

The first recorded ascent took place in 1908 when guide Sidney Unwin led explorer Mary Schäffer to Maligne Lake during her expedition. The peak was later named after this guide and received official recognition from Canada's Geographical Names Board in 1947.

Mary Schäffer named the peak in 1908 for Sidney Unwin, the guide who climbed it while helping her search for Maligne Lake; she also named Mount Charlton, Maligne Mountain and Mount Warren. The name became official in 1947 through the Geographical Names Board of Canada.
