Mount Thor, officially gazetted as Thor Peak, is a mountain with an elevation of 1,675 m (5,495 ft) located in Auyuittuq National Park, on Baffin Island, Nunavut, Canada. The mountain is located 46 km (29 mi) northeast of Pangnirtung and features the Earth’s greatest purely vertical drop at 1,250 m (4,101 ft), with an average angle of 105 degrees.

This feature makes the site popular with climbers, despite its remoteness. Camping is allowed, with the only official site being at the entrance to the Akshayuk Valley near Overlord Peak.

Donald Morton and Lyman Spitzer made the first ascent of Mount Thor in 1965 during the Alpine Club of Canada expedition led by Pat Baird. The world record for longest rappel was set on Mount Thor, July 23, 2006, by an American team consisting of: Chuck Constable, Dirk Siron, Ben Holley, Kenneth Waite, Gordon Rosser, Donny Opperman, Deldon Barfuss, and Tim Hudson.
