The District of Athabasca is a former district of Canada. Its northern boundary was the current southern boundary of the Northwest Territories and extended south to 55° north latitude. The westernmost part is now part of Alberta and most of the eastern part is now in Saskatchewan. The very easternmost part is now part of Manitoba. Created in 1882 out of the Northwest Territories, it was expanded into modern Saskatchewan in 1885. It ceased to exist in 1905.
