Otsego County is a county in the U.S. state of New York. As of the 2010 census, the population was 62,259.  The county seat is Cooperstown.  The name Otsego is from a Mohawk or Oneida word meaning "place of the rock." 
In 1789, Ontario County was split off from Montgomery. The area split off from Montgomery County was much larger than the present county, as it included the present Allegany, Cattaraugus, Chautauqua, Erie, Genesee, Livingston, Monroe, Niagara, Orleans, Steuben, Wyoming, Yates, and part of Schuyler and Wayne counties.
Otsego County was one of three early counties split off from Montgomery (the other two being Herkimer and Tioga) after the American Revolutionary War. Otsego County was officially established on February 16, 1791, with Cooperstown as its county seat, although at the time the village of Cherry Valley was much larger. The original county consisted of three large townships:
Otsego and Cherry Valley together roughly covered the area of modern Otsego County, while Harpersfield covered the area south of the current county as far as the Delaware River.
The original appointments to Otsego County government positions, made by Governor George Clinton included:
- Richard R. Smith, county sheriff, from Otsego township,
- Jacob Morris, county clerk, from Otsego township,
- William Cooper, chief judge, from Otsego township,
- Jedediah Peck, associate justice from Otsego township,
- Edward Griswold, associate justice from Cherry Valley
- Platt Townsend, associate justice from Harpersfield,
- Alexander Harper, commander of the county militia, from Harpersfield.
By 1793, four towns had been added to the county by division of the existing towns:

The Village of Cooperstown (home of James Fenimore Cooper, whose father William Cooper founded it) is located at the south end of Otsego Lake. It attracts many tourists to the Baseball Hall of Fame and the New York State Historical Association museums. Cultural attractions also include the Glimmerglass Opera, with a summer season that draws many repeat visitors for stays.
The primary contributor to the economy is healthcare: Bassett Medical Center, the headquarters of Bassett Healthcare Network and its more than 3,000 employees, is located here.
The City of Oneonta has two institutions of higher education: Hartwick College and the State University of New York at Oneonta; A.O. Fox Memorial Hospital, an affiliate of the Bassett Network; major retail activity; and numerous small businesses. The county as a whole remains relatively rural, with dairy farming a contributing industry that has consolidated employment in recent years, although production has remained steady.
