Thomas Dongan, the fourth royal governor of New York, was granted an 800-acre parcel of land in 1683 that included New Hyde Park.

[2] The northern, unincorporated part of New Hyde Park was home to several notable events: Shelter Rock, deposited during the last glacial period and marking the southern extent of that event; in 1908, the Vanderbilt Motor Parkway (later known as the Old Motor Parkway), the first limited access highway in the world and used for auto racing; from 1946 to 1947, home to the United Nations at the Sperry Gyroscope building on Marcus Avenue.

[6] According to the United States Census Bureau, the village has a total area of 0.8 square miles (2.1 km2), all land.

In addition, a small section of the New Hyde Park postal zone extends into the village of North Hills, also in Nassau County.

Finally, a small area of Queens called Glen Oaks is provided mail service by the New Hyde Park 11040 post office.

Because of its close proximity and relatively short commute to Manhattan, it is primarily a commuter village with over 75% of the land used for single family residences, but also has warehouses near the Long Island Rail Road station and retail districts along Jericho Turnpike.

[8] Northwell Health, the largest employer on Long Island, is headquartered in New Hyde Park.

Prior to gentrification, New Hyde Park had previously been home to more industrial companies including Techem, Inc., which manufactured acid-based chromium, cadmium, cyanide, nickel, and zinc electroplating solutions from 1973 to 1994.

[9] Stock Drive Products and Sterling Instrument machine and manufacture more than 130,000 kinds of mechanical components.

The companies are owned by Designatronics Inc.[10] As of the census[12] of 2010, there were 9,712 people, 3,290 households, and 2,569 families living in the village.

[14] As of October 2021, the Mayor of New Hyde Park is Christopher Devane, the Deputy Mayor is Madhvi Nijjar, and the Village Trustees are Rainer Burger, Madhvi Nijjar, Arthur Savarese, and Donna M.

[14] Most of the Village of New Hyde Park is located within the boundaries of (and is thus served by) the New Hyde Park-Garden City Park School District, while some of it is zoned to the Elmont Union Free School District (both of which serve students in grades K-6).

As of 1997[update] some areas with New Hyde Park addresses that are in unincorporated areas are within the Great Neck Union Free School District or the Herricks Union Free School District.
