The Thelon River (Inuktitut: Akilinik, lit. "on the other side") stretches 900 kilometres (560 mi) across northern Canada. Its source is Whitefish Lake in the Northwest Territories, and it flows east to Baker Lake in Nunavut. The Thelon ultimately drains into Hudson Bay at Chesterfield Inlet.
The drainage basin of the Thelon River encompasses some 142,400 square kilometres (55,000 sq mi). Located far from almost all human development, the Thelon and its surroundings are entirely pristine wilderness. It has been described as Canada's remotest river.
The river has a width of up to a kilometer (0.6 mi) along much of its lower section, widening into Beverly, Aberdeen, and Schultz Lakes about 100 kilometres (62 mi) upstream from its mouth at Baker Lake.
The Inuit people, including Caribou Inuit and Copper Inuit, have long occupied the sparsely-populated lands around the Thelon. Artifacts of Inuit hunting and travel (including inukshuk guide stones) are readily observed near the river.
In 1770–71, English explorer Samuel Hearne crossed the Thelon while exploring Canada's northern interior.
Over the winter of 1926–27, Canadian naturalist John Hornby starved to death on the Thelon along with two other men. They had planned to hunt migrating caribou, but failed to find the herd. Nevertheless, on the basis of Hornby's earlier explorations with James Critchell-Bullock in 1923, the Thelon Game Sanctuary was established in 1927, renamed the Thelon Wildlife Sanctuary in 1956.
In 1927(?), the Norwegian explorer and writer Helge Ingstad went by dog sled to the headwaters of the Thelon (Lynx Lake) together with native peoples from the east end of Great Slave Lake. This he detailed in his book The Land of Feast and Famine.
In 1990, the lower 545 kilometres (339 mi) of the Thelon were designated a Canadian Heritage River. Although there is no road access to the river, a number of wilderness campers and canoeists visit the Thelon every summer.
The basin of the Thelon is mentioned in the 1979 sci-fi novel Beetle in the Anthill by Boris and Arkady Strugatsky as the location of the embassy of Golovans: intelligent canoid (dog-like) race evolved at Saraksh planet.
