The Northern Saskatchewan Administration District (NSAD) is the unorganized area of the Canadian province of Saskatchewan. It encompasses approximately half of Saskatchewan's land mass. Despite its extent, the majority of Saskatchewanians live in the southern half of the province, while the majority of northern Saskatchewanians live in incorporated municipalities outside the NSAD's jurisdiction. As a result, the 2016 census, which refers to the area as Unorganized Division No. 18, counted only 1,115 residents, which placed its population density at 250 square kilometres for every inhabitant. The district has no local government and is directly subject to the Minister of Government Relations.^[1]

An unincorporated Northern Saskatchewan region was first established by the 1948 Northern Administration Act.^[1]
