Uummannaq Island is a small 12 sq. km island in the Qaasuitsup municipality in northwestern Greenland. Located in the south-central part of the Uummannaq Fjord, it is home to the most prominent mountain on the Arctic coast of western Greenland and to Uummannaq, the largest town north of Ilulissat.
entirely dominates the landscape of the island, its base occupying its entire northern half. The island has a very undeveloped coast, with a handful of small, rocky bays primarily in the southermost, inhabited part. The only significant bay is Qasigissat on the southwestern shore. The Uummannaq port occupies a small inlet in the southeastern end of the island. It is not deep enough to service large cruise ships, but sufficiently deep to handle supply and fishing ships of Royal Arctic Line and Royal Greenland, as well as motorboats and lesser fishing boats.
There are two significant lakes on the island: Tasersuaq lake, and the Blue Lake. There are also several tiny ponds on the plateau, south of Uummannaq Mountain. The island is well connected with the rest of Greenland. Air Greenland has its regional helicopter hub on the island, serving all settlements in the region. Several daily helicopter flights link the island with the nearby Qaarsut Airport on Nuussuaq Peninsula, from where STOL connections are available to Upernavik, Sisimiut, Ilulissat and further to central and southern Greenland.
