Herkimer County is a county in the U.S. state of New York. As of the 2020 census, the population was 60,139. Its county seat is Herkimer. The county was created in 1791 north of the Mohawk River out of part of Montgomery County. It is named after General Nicholas Herkimer, who died from battle wounds in 1777 after taking part in the Battle of Oriskany during the Revolutionary War.

Herkimer County is part of the Utica–Rome Metropolitan Statistical Area.

In 1791, Herkimer County was created as one of three counties split off from Montgomery (the other two being Otsego and Tioga counties) as New York State was developed after the American Revolutionary War. Its area was much larger than the present county, however, and was reduced subsequently as more counties were organized.

Part of Herkimer County was included in the Macomb's Purchase of 1791, during the wide-scale sale of public lands after the state forced Iroquois tribes allied with the British during the war to cede their territory. Suddenly the state was selling 5 million acres (20,000 km2) of land in upstate, central and western New York.

In 1794, Onondaga County was split off from Herkimer County. This county was larger than the current Onondaga County, and included the present Cayuga, Cortland, and part of Oswego counties.

In 1798, portions of Herkimer and Tioga counties were taken to form Chenango County.

Another part of Herkimer was split off to form Oneida County. It was then larger than the current Oneida County, including the present Jefferson, Lewis, and part of Oswego counties.

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

During the American Civil War, Herkimer contributed five companies to the 34th New York Volunteer Infantry Regiment, leading to the unit's nickname "The Herkimer Regiment".


According to the U.S. Census Bureau, the county has a total area of 1,458 square miles (3,780 km2), of which 1,411 square miles (3,650 km2) is land and 46 square miles (120 km2) (3.2%) is water.

Herkimer County is in central New York State, northwest of Albany, and east of Syracuse. The northern part of the county is in the Adirondack Park. The Mohawk River flows across the south part of the county.
