Kugluktuk (Inuktitut: Qurluqtuq, ;[4] Inuktitut syllabics: Inuktitut: ᖁᕐᓗᖅᑐᖅ; in Inuktitut pronounced as /quʁluqtuq/), known as Coppermine until 1 January 1996, is a hamlet at the mouth of the Coppermine River in the Kitikmeot Region of Nunavut, Canada, on Coronation Gulf, southwest of Victoria Island. It is Nunavut's westernmost community, near the border with the Northwest Territories.
The area's traditional language is Inuinnaqtun, which is written in the Latin alphabet, rather than the syllabics of the Inuktitut writing system. Like Cambridge Bay, Bathurst Inlet, and Umingmaktok, syllabics are rarely seen and are used mainly by the Government of Nunavut.
Prior to European contact, Dene travelled to the area and interacted acrimoniously with nearby Thule and Inuit, sometimes ending in deadly raids against each other (see Bloody Falls massacre). Between 1913 and 1916, anthropologist Diamond Jenness studied and recorded the traditional lifestyle of Inuit around Kugluktuk. The Hudson Bay Company established a trading post at this community in 1927 while the Royal Canadian Mounted Police (RCM)P built a police station in 1932. The former name of the community, Coppermine, was named after its namesake Coppermine River.
In 1982, a division plebiscite was held. About 80% of the population in what is now Nunavut voted in favour of division; Coppermine was one of only two communities to vote against it, Cambridge Bay was the other.[5]
In 1996, a healing ceremony between Dene and Inuit took place to reconcile for historical grievances. The community also changed its name from Coppermine to Kugluktuk. In June 2004, a fuel line broke in the centre of Kugluktuk, spilling of diesel fuel.
As a census subdivision in the 2021 Canadian census conducted by Statistics Canada, Kugluktuk had a population of 1,382 living in 397 of its 438 total private dwellings, a change of from its 2016 population of 1,491. With a land area of, it had a population density of in 2021.[6]

The community has been served by the Qiniq network since 2005. Qiniq is a fixed wireless service to homes and businesses, connecting to the outside world via a satellite backbone. The Qiniq network is designed and operated by SSi Canada. In 2017, the network was upgraded to 4G LTE technology, and 2G-GSM for mobile voice.
Kugluktuk's two schools are Kugluktuk High School and Jimmy Hikok Ilihakvik.
