Kimmirut (Syllabics: ᑭᒻᒥᕈᑦ [kimːiɢut]; known as Lake Harbour until 1 January 1996) is a community in the Qikiqtaaluk Region, Nunavut, Canada.

A proposal in 2005 for a road to Iqaluit was determined to be impractical owing to roundabout routing over the mountains.

Qiniq is a fixed wireless service to homes and businesses, connecting to the outside world via a satellite backbone.

The city has cold winters and short summers that are too cool to permit the growth of trees.

Kimmirut averages just over 335 mm (13.2 in) of precipitation annually, wetter than many other localities in the Arctic Archipelago, with the summer being the wettest season.
