Maple Mountain is a mountain, located within Lady Evelyn-Smoothwater Provincial Park, Temagami, Ontario, Canada, estimated 642 m (2,106 ft) above mean sea level. It has a higher vertical rise over the surrounding landscape, 37 m (121 ft) higher than the Ishpatina Ridge, which is the highest point of land in Ontario rising over Scarecrow Lake. Maple Mountain rises over Tupper Lake and is considerably better known than Ishpatina Ridge. It ranks thirteenth, but when ranked by vertical rise it is the highest of the top 25 peaks in Ontario.
The 100-ft abandoned fire tower is also still intact and attracts many hikers. A 3.2 kilometre long hiking trail leads to the abandoned fire tower. The abandoned ranger cabin is located at the trail head near the lake..
Located in Timiskaming District of Northeastern Ontario, the mountain is not very accessible; roads and trails in the remote area are difficult to travel in poor weather. The most popular approach routes to Maple Mountain are by canoe and/or float plane.
The indigenous Temagami First Nation call the mountain Chee-bay-jing, meaning "the place where the spirits go" and consider it a sacred site. The English name of the mountain was given by Dr. Robert Bell of the Geological Survey of Canada in 1888. Bell was the first known non-aboriginal to scale the mountain.
9 people died in 1981 in aircraft crashes here, adding to the legend of the mountain.
