Coös County or Coos County (/ˈkoʊ.ɒs/, with two syllables) is the northernmost county in the U.S. state of New Hampshire. As of the 2020 census, the population was 31,268, making it the least-populated county in the state. The county seat is Lancaster.
Coös County is part of the Berlin, NH–VT Micropolitan Statistical Area. It is the only New Hampshire county on the Canada–United States border, south of the province of Quebec, and thus is home to New Hampshire's only international port of entry, the Pittsburg–Chartierville Border Crossing. The only city in Coös County is Berlin, with the rest of the communities being towns, or unincorporated townships, gores and grants.
Major industries in Coös County include forestry and tourism, with the once-dominant paper-making industry in sharp decline. The county straddles two of the state's tourism regions. The southernmost portion of the county is part of the White Mountains Region and is home to Mount Washington. The remainder of the county is known as the Great North Woods Region, or known locally as the North Country.
