Nyack (/ˈnaɪ.æk/ ⓘ) is a village primarily located in the town of Orangetown in Rockland County, New York, United States.

Named after the Native Americans who resided there before European colonization, the village consists mostly of low-rise buildings on hilly terrain along the western shore of the Hudson River.

Adjacent South Nyack is the western terminus of the Tappan Zee Bridge, which connects to Tarrytown in Westchester County via U.S. Interstate 87, an important commuter route.

Native American stone relics and oyster middenss found along the Hudson River shoreline indicate that present-day Nyack was a popular pre-Colonial fishing location.

A letter from 1687 is on file in the State Archives in Albany petitioning Governor Dongan to buy a strip of land in the west hills of Tappan (today Nyack), where he had lived for 12 years.

Letter dated 31 August 1687 on file at New York State Archives at Albany: The humble Peticon of Harman Dowse of Tappan Neare Ye River Side, Alias New Orania farm ... your peticonr is a farmer that hath nothing wot comes by his hard labour but by God's Blessing out ye Produce and ye ground, and hath a family to provide for.A plaque installed in 1938 on the north wall of the Key Bank building at South Broadway and Burd Street in Nyack reads: The Tappan Indians, from time immemorial, occupied these lands fronting the river shore.

In Algonkian dialect spoken by them they called this location NAY-ACK which means the fishing place.

The first settlement of white people within the limits of the present Rockland County, New York, took place in 1675 when Harmen Dowesen (Tallman), a young Dutchman of Bergen, New Jersey relocated here.The Tallmans erected a mill on a stream still known as Mill Brook.

As town government was no longer seen as an effective way to deal with the community's needs, village incorporation was discussed.

Unofficially nicknamed the "Rockies", the Rocklands played as members of the Class D level North Atlantic League from 1946 to 1948 and were an affiliate of the Philadelphia Athletics in 1947.

In the 1980s, the village underwent a major urban revitalization project to commercialize the downtown area and to expand its economy.

The Helen Hayes Theatre was built, and the downtown area became home to many new business establishments.

In 1991, the landmark court case Stambovsky v. Ackley ruled that a house at 1 LaVeta Place on the Hudson River was a legally haunted and that the owner (but not the real estate agent) was required to disclose that to prospective buyers.

The owner, Helen Ackley, had earlier organized haunted house tours and was party to an article about it in Reader's Digest.

The company's 1949 Ahrens-Fox fire engine was polished to bright, gleaming red and is still in use after more than 50 years.

Nyack is on the west bank of the Hudson River, north of the Tappan Zee Bridge.

Nyack was formerly served by the Northern Branch of the Erie Railroad, with service to Pavonia Terminal in Jersey City.
