Schuyler Flatts is an important prehistoric and historic settlement site overlooking the Hudson River in Colonie, New York. The site includes evidence of prehistoric Native American, early Dutch colonial settlement, and 18th and 19th-century American use. Because of this rich confluence of archaeological sites, the area was designated a National Historic Landmark in 1993. It is now owned by the town of Colonie, and is known as Schuyler Flatts Cultural Park.
