Mechanicville is a city in Saratoga County, New York, United States. The population is 5,196 as of the 2010 census. It is the smallest city by area in the state. The name is derived from the occupations of early residents.
The city is located on the eastern border of Saratoga County and is north of Albany, the state capital. Mechanicville borders the towns of Stillwater (of which it was once a part) and Halfmoon in the county, and the town of Schaghticoke, in Rensselaer County.
The first European settlers on the Tenendeho Creek in the area of today's Mechanicville arrived in 1764. Actually, the first listing for a settlement on Thenendehowa Creek is in 1721. At that time, Cornelius Van Buren had a sawmill at the mouth of the creek where it emptied into the Hudson. The first documented occurrence of the name "Mechanicville" dates back to 1829. The name comes from the early settlers, who were independent mastercraftsmen such as millers, carpenters, or butchers, whose professions were commonly known as the "mechanical arts" at the time.
