Kinderhook is a town in the northern part of Columbia County, New York, United States. The population was 8,498 at the 2010 census, the most populous municipality in Columbia County. The name of the town means “Children’s Corner” in the language of the original Dutch settlers (Kinderhoek). The name “Kinderhook” has its root in the landing of Henry Hudson in the area around present-day Stuyvesant, where he was greeted by Native Americans with many children.
