Hamilton County is a county in the U.S. state of New York. As of the 2020 census, the population was 5,107, making it the least populous county of New York, and the only county with less than 10,000 residents. With a land area nearly the size of Delaware, it is the least densely populated county east of the Mississippi River. Its county seat is Lake Pleasant. The county was created in 1816 and organized in 1847. The county is part of the North Country region of the state.

Hamilton County is one of only two counties that lie entirely within the Adirondack Park (Essex being the other). Because of its location in the park, any development in the county is restricted by the New York State Constitution, which designates the park as "forever wild." There are no permanent traffic lights in the county, and much of the county has no cell phone service.

Etymology

The county is named after Alexander Hamilton, the only member of the New York State delegation who signed the United States Constitution in 1787, and was later the first United States Secretary of the Treasury.

History

On April 12, 1816, Hamilton County was created by partitioning 1,800 square miles (4,700 km²) from Montgomery County, but due to low population it remained unorganized and administered from Montgomery County, N.Y. until it was recognized as sufficiently prepared for self-government on January 1, 1838. The organization process was completed by summer 1847.

On April 6, 1860, Fulton County, which had been partitioned April 18, 1838, had 10 square miles (26 km²) of land in Sacandaga Park transferred to Hamilton County. On May 24, 1915, land was swapped between Hamilton and Essex counties, with Hamilton ceding Fishing Brook Mountain for Indian Lake. Hamilton gained an additional 20 square miles (52 km²), whereas Essex County lost 30 square miles (78 km²). This left Hamilton with its present size of 1,830 square miles (4,700 km²).

The former town of Gilman was dissolved in 1860. The original county seat was Sageville, now part of Lake Pleasant.
