Region 3 is the name of a Statistics Canada census division, one of six in the Northwest Territories, Canada. It was introduced in the 2011 census, along with Regions 1, 2, 4, 5, and 6, resulting in the abolition of the former census divisions of Fort Smith Region and Inuvik Region (the latter not to be confused with the modern-day administrative region of the same name).
It is located within the North Slave Region administrative region and is entirely surrounded by Region 6. The region has the same communities as the Monfwi electoral district.
The 2011 census reported a population of 2,812 and a land area of 25,080.94 km2 (9,683.81 sq mi).
