Clinton County is a county in the north-easternmost corner of the state of New York, in the United States and bordered by the Canadian province of Quebec. As of the 2020 United States Census, the population was 79,843. Its county seat is the city of Plattsburgh. The county lies just south of the border with the Canadian province of Quebec and to the west of the State of Vermont.

The county is named for George Clinton, the first Governor of New York, who later was elected as Vice President. He had been a Founding Father who represented New York in the Continental Congress.

Clinton County comprises the Plattsburgh, New York Micropolitan statistical area.

When counties were established in New York State in 1683, the present Clinton County was part of Albany County. This was an enormous county, including the northern part of New York State as well as all of the present state of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766, by the creation of Cumberland County, and further on March 16, 1770, by the creation of Gloucester County, both containing territory now in Vermont. On March 12, 1772, what was left of Albany County was split into three parts, one remaining under the name Albany County. One of the other pieces, Charlotte County, contained the eastern portion.

In 1784, the name "Charlotte County" was changed to Washington County to honor George Washington, the American Revolutionary War general and later President of the United States of America.

In 1788, Clinton County was split off from Washington County. This was a much larger area than the present Clinton County, including several other counties or county parts of the present New York State.

In 1799, Essex County was split off from Clinton County.

In 1802, parts of Clinton, Herkimer, and Montgomery counties were taken to form the new St. Lawrence County.

In 1808, Franklin County was split off from Clinton County.


According to the U.S. Census Bureau, the county has a total area of 1,118 square miles (2,900 km2), of which 1,038 square miles (2,690 km2) is land and 80 square miles (210 km2) (7.1%) is water.

Clinton County is in the northeastern part of the State of New York, west of Vermont and south of the Canadian province of Quebec. The eastern boundary of Clinton County is Lake Champlain, which serves as the New York-Vermont border. Because of this, the encompassing region is referred to as the Adirondack Coast. The Ausable River forms a large part of the south county line.

The southwest part of the county is in the Adirondack Park.
