Nyack is a village incorporated in 1872 primarily in the town of Orangetown, with a very small western section in Clarkstown, in Rockland County, New York, United States.Nyack had a population of 6,765 as of the 2010 census.
Stone Native American relics and heaps of oyster shells found along the shore of the Hudson indicate that this was a favorite fishing spot of the natives. In 1675, the first Europeans settled in Rockland County at Nyack.Harman Douwenszen came to America as a toddler and grew up in Bergen, New Jersey. He settled his father's rough land that is today Nyack. The Tappan Register of 1707 claimed it was pronounced Nay-ack. Harman was thought to be the first white settler. In the State Archives in Albany there is a 1687 letter on file petitioning Governor Dongan to buy a strip of land in the west hills of Tappan (today Nyack), in which he had lived on for 12 years. His partition was granted and he bought the land from the Native Americans. He called his farm New Orania (Oranje in Dutch). This section of Nyack became known as Orangetown in 1683. Nyack became part of Rockland County in 1798. Nyack became an incorporated village in 1872 according to the same plaque on the Midland Trust Building.
