Region 4 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, 3, 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).
Its territory coincides roughly with the Dehcho Region and the extreme western part of South Slave Region that is centered on Fort Providence, west of Great Slave Lake.
The 2011 census reported a population of 3,246 and a land area of 194,494.08 km2 (75,094.58 sq mi).
Main languages in the Region include English (62.8%), Slavey (33.6%) and Dene (1.7%).
