Marc-André Leclerc was a Canadian rock climber, ice and mixed climber, and alpinist. He is known for his solo ascents–often in winter–of major ice and alpine climbing routes. In 2016, he completed the first winter solo ascents of both Torre Egger in Patagonia and of the Emperor Face of Mount Robson in Canada. In 2018, he was killed in an avalanche on the Mendenhall Towers in Alaska. In 2021, a documentary film called The Alpinist was released about Leclerc's life and climbs.
