St. Lawrence County, New York is a county located in the far northern region of New York, bordering the Canadian province of Ontario.

History

The region was historically part of the territory of the Iroquois Confederacy, specifically the Mohawk and Onondaga peoples, before European exploration. Following the American Revolutionary War, the area was included in the Macomb's Purchase, a massive land acquisition by Alexander Macomb. Settlement accelerated after the construction of the Erie Canal, which connected the Great Lakes to the Hudson River. The county was officially organized in 1802 and named for the Saint Lawrence River, which forms its northern border. Key historical events include the development of the St. Lawrence Seaway and hydroelectric projects at Massena in the mid-20th century, which transformed the local economy. The Battle of Ogdensburg during the War of 1812 was a notable military engagement within the county.
