Paulatuk (pronunciation^ⓘ) is a hamlet located in the Inuvik Region of the Northwest Territories, Canada. It is located adjacent to Darnley Bay, in the Amundsen Gulf, and 105 km (65 mi) east of the Smoking Hills. The town was named for the coal that was found in the area in the 1920s, and the Siglitun spelling is Paulatuuq^{[pronunciation?]}, "place of coal".

The area has been inhabited by humans, including the Thule and Copper Inuit, since roughly 1000 CE. Most recently, it is part of the Inuvialuit Settlement Region.

The hamlet dates back as early as the 1920s when several Inuit settled at this site on Darnley Bay, however the community only became permanently occupied following the opening of a trading post in 1935.

Paulatuk was incorporated as a hamlet in 1987 and celebrated the 50th anniversary of its settlement in 2015.

In the 2021 Canadian census conducted by Statistics Canada, Paulatuk had a population of 298 living in 81 of its 100 total private dwellings, a change of 12.5% from its 2016 population of 265. With a land area of 63.58 km² (24.55 sq mi), it had a population density of 4.7/km² (12.1/sq mi) in 2021.

In the 2016 census 235 people were listed as Indigenous and all were Inuit (Inuvialuit). The two principal languages spoken in Paulatuk are Inuinnaqtun (Inuvialuktun) and English.

European settlement began when the Roman Catholic Church opened a trading post. In the 1950s a Distant Early Warning Line site was built about 95 km (59 mi) to the northwest at Cape Parry, on the Parry Peninsula, providing a wage-based income for the community. The trading post was taken over by the local co-op and today the local store is part of The North West Company.

Hunting, fishing and trapping are major economic activities, but in recent years art printmaking has played an increasing role in the local economy.
