Coös County (pronounced "koh-oss") is a county in the state of New Hampshire. In 2020, it had 31,268 people, making it the least populated county in New Hampshire. The main town where the county government is located is Lancaster.

Coös County is special because it's the only county in New Hampshire that shares a border with Canada. It's located just south of the province of Quebec. This means it has New Hampshire's only international border crossing, called the Pittsburg–Chartierville Border Crossing. The only city in Coös County is Berlin. All other communities are towns or special areas called townships, gores, and grants.

This county covers the northernmost part of New Hampshire. Its main industries are forestry (working with trees and wood) and tourism (people visiting for fun). The paper-making industry, which used to be very big, has become much smaller. Coös County is part of two of New Hampshire's tourism areas. The southern part is in the White Mountains Region and is home to Mount Washington, the highest peak in the northeastern United States. The rest of the county is known as the Great North Woods Region, or simply the North Country.

What's in a Name?

The name Coös comes from an old Native American word from the Cowasuck people. It means "small pines." This county is one of only two in the United States that has a special mark (called a diaeresis) over one of its letters.

Sometimes, you'll see the name written with two dots over the "o" (Coös) to show that it has two syllables when you say it. The county government uses both spellings.

A Look Back in Time

Coös County was created on December 24, 1803. It was formed from the northern part of Grafton County, New Hampshire. At first, the county government was in Berlin, but it later moved to Lancaster.

During the American Revolutionary War, two groups of soldiers, called Bedel's Regiment and Whitcomb's Rangers, were formed from the people living in Coös. After the war, there was a disagreement about the border between the northern tip of the county and Canada. For a few years, the people in that area even formed their own independent place called the Republic of Indian Stream!

In 1810, about 4,000 people lived here. By 1870, the population had grown to almost 15,000. Besides farming, early industries included working with wood (forestry) and making things in factories.

Exploring the Geography

NH Coos Co towns map
This map shows the towns in Coös County. Towns in black have their own records, while green areas are unincorporated and don't keep records.

Coös County covers about 1,830 square miles. Most of this is land (about 1,795 square miles), and a smaller part is water (about 35 square miles). It's the largest county in New Hampshire by size. It borders both Vermont and Maine, as well as Canada.

A lot of the county's mountainous areas are protected. These include parts of the White Mountain National Forest, wilderness areas, and state parks. These protected lands cover most of the northern White Mountains. This includes all the famous peaks of the Presidential Range, like Mount Washington, which is the tallest mountain in the Northeast. The Cohos Trail, a long hiking path, runs for 162 miles through the county.

Important roads in Coös County include New Hampshire Route 16, which runs near the Maine border and through Berlin. New Hampshire Route 26 goes through the Great North Woods. Two major U.S. Highways are U.S. Route 2, which crosses the county from Lancaster, and U.S. Route 3, which goes all the way to the Canadian border.

Coös County has the fewest people of all New Hampshire counties. It's also unique because it has a lot of "unincorporated land." This means that over half of its areas are not organized into towns or cities. Instead, they are townships, gores, or grants. Very few people live in these unincorporated areas. For example, only three of them (Wentworth Location, Millsfield, and Cambridge) had more than ten people in recent counts. About one-third of the county's population lives in Berlin, which is the only city and the main economic center. Lancaster is where the county government is located.
