The Thompson–Nicola Regional District is a regional district in the Canadian province of British Columbia. The Canada 2021 Census population was 143,680 and the area covers 44,449.49 square kilometres. The administrative offices are in the main population centre of Kamloops, which accounts for 78 percent of the regional district's population. The only other city is Merritt; other municipally-incorporated communities include the District Municipalities of Logan Lake, Barriere and Clearwater and the Villages of Chase, Ashcroft, Cache Creek, Clinton and Lytton, and also the Mountain Resort Municipality of Sun Peaks. The region is named indirectly for the Thompson River by way of the traditional regional names of "the Thompson Country" and "the Nicola Country"; the Nicola Country was named for Chief Nicola and was originally "Nicola's Country", where he held sway; he is also the namesake of that river. The regional district government operates over 15 services including libraries, solid waste management and recycling, emergency and development services, plus a film commission. The region is unique in Canada as it consistently holds around some of the hottest summer temperatures in the country, while also containing an area around Ashcroft that may be the only arid climate in Canada.
