Qaasuitsup (in Kalaallisut; Greenlandic pronounced as /qaːsuitt͡sup̚/, Place of Polar Darkness) was a municipality in Greenland, operational from 1 January 2009[1] to 31 December 2017.[2] As of January 2015, its population was 17,168.[3] The administrative centre of the municipality was in Ilulissat (formerly called Jakobshavn).
The municipality consisted of the former municipalities of western and northern Greenland, each named after the biggest settlement:
Effective 1 January 2018, Qaasuitsup Kommunia was partitioned into two new municipalities:
The municipality was located in northwestern Greenland. With an area of 6600001NaN1,[4] it was the largest municipality in the world by area,[5] larger than France at 6434271NaN1.[6]
In the south, it was flanked by the Qeqqata municipality. In the southeast, it was bordered by the Sermersooq municipality, however this border ran north–south (45° West meridian) through the center of the Greenland ice sheet (Kalaallisut; Greenlandic: Sermersuaq), and as such was free of traffic. In the east and northeast it was bordered by the Northeast Greenland National Park.
At the southern end of the municipal coastline were the waters of Disko Bay, an inlet of the larger Baffin Bay, which to the north edges into the island of Greenland in the form of Melville Bay. The coastline of northeastern Baffin Bay is dotted with islands of the Upernavik Archipelago, which was entirely contained within the municipality. In the far northwest near Qaanaaq and Siorapaluk, the municipal shores extended into Nares Strait, which separates Greenland from Ellesmere Island.
Denmark claimed Hans Island as part of Qaasuitsup (now Avannaata), while Canada considers it to be part of the Nunavut region of Qikiqtaaluk.
