St. Lawrence County is a county in the U.S. state of New York. As of the 2010 census, the population was 111,944. The county seat is Canton. The county is named for the Saint Lawrence River, which in turn was named for the Christian saint Lawrence of Rome, on whose Feast day the river was visited by French explorer Jacques Cartier.
When counties were established in the Province of New York in 1683, the present St. Lawrence County was part of Albany County. This was an enormous territory, 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. The 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. The other two were called Tryon County (later renamed Montgomery County) and Charlotte County (later renamed Washington County). Tryon County contained the western portion (and, since no western boundary was specified, theoretically extended west to the Pacific). The eastern boundary of Tryon County was approximately five miles west of the present city of Schenectady, and the county included the western part of the Adirondack Mountains and the area west of the West Branch of the Delaware River. The area then designated as Tryon County includes what are now 37 counties of New York State. The county was named for William Tryon, colonial governor of New York. Charlotte County contained the eastern portion of Albany County.
In 1784, following the peace treaty that ended the American Revolutionary War, 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. Tryon County was changed to Montgomery County to honor the general, Richard Montgomery, who had captured several places in Canada and died trying to capture the city of Quebec; it replaced the name of the hated British governor.
In 1788, Clinton County was split off from Washington County. This was a much larger area than the present Clinton County, including part of what would later become St. Lawrence County, as well as several other counties or county parts of the present New York State.
In 1789, the size of Montgomery County was reduced by the splitting off of Ontario County from Montgomery. The actual area split off from Montgomery County was much larger than the present county, also including the present Allegany, Cattaraugus, Chautauqua, Erie, Genesee, Livingston, Monroe, Niagara, Orleans, Steuben, Wyoming, Yates, and part of Schuyler and Wayne Counties.
St. Lawrence County is part of Macomb's Purchase of 1791.
In 1791, Herkimer County was one of three counties split off from Montgomery (the other two being Otsego, and Tioga County). This was much larger than the present county, however, and was reduced by a number of subsequent splits. The first was the splitting off in 1794 of Onondaga County. This county was larger than the current Onondaga County, including the present Cayuga, Cortland, and part of Oswego Counties. This was followed by the splitting off in 1798 from Herkimer County of two portions: one, Oneida County, was larger than the current Oneida County, including the present Jefferson, Lewis, and part of Oswego Counties; another portion, together with a portion of Tioga County, was taken to form Chenango County.
In 1799, Clinton County was reduced in size by the splitting off of Essex County from Clinton County.
In 1802, parts of Clinton, Herkimer, and Montgomery Counties were taken to form the new St. Lawrence County. At that time Ogdensburg was the county seat. In 1828 the county seat was moved to Canton. The selection of Canton as the county was a compromise by the state legislature to end competition between factions supporting Ogdensburg and Potsdam for the county seat.
On September 5, 1944, a 5.8 magnitude earthquake centered in Massena struck the county. The earthquake was felt from Canada south to Maryland, and from Maine west to Indiana. The earthquake was the strongest earthquake in New York State history.
According to the United States Census Bureau, the county has a total area of 2,821 square miles (7,310 km2), of which 2,680 square miles (6,900 km2) is land and 141 square miles (370 km2) (5.0%) is water. It is the largest county by area in New York. It is larger than the entire state of Rhode Island (1544.9 square miles) and the state of Delaware (2488.72 square miles).

Universities and colleges
Prior to the 1992 Presidential Election, St. Lawrence County was a traditionally Republican county, supporting the Democrats only in their sweep of New York State counties in 1964. From 1992 through the 2012 election, St. Lawrence County swung Democratic, posting double-digit victories for Democratic candidates, most notably in 1996 when Bill Clinton won the county by 28-point margin over Bob Dole. The first Republican victory in the county since 1988 came in 2016 when Donald Trump carried the county by an eight-point margin. In 2020, it was one of only a few counties in Upstate New York where Trump improved his margin, this time carrying it by over 10 points.
