Kivalliq Region (Inuktitut syllabics: ᑭᕙᓪᓕᖅ ) is an administrative region of Nunavut, Canada. It consists of the portion of the mainland to the west of Hudson Bay together with Southampton Island and Coats Island. The regional seat is Rankin Inlet (pop. 2,266). The population was 8,955 in 2011.
Before 1999, Kivalliq Region existed under slightly different boundaries as Keewatin Region, Northwest Territories. Although the Kivalliq name became official in 1999, Statistics Canada has continued to refer to the area as Keewatin Region, Nunavut in publications such as the Census. Most references to the area as "Keewatin" have generally been phased out by Nunavut-based bodies, as that name was originally rooted in a region of northwestern Ontario, and only saw application onto Inuit-inhabited lands because of the boundaries of the now-defunct District of Keewatin.
