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

It is located on the shore of Hudson Strait on Baffin Island's Meta Incognita Peninsula.

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.

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.
