Manorhaven is a village in Nassau County, on the North Shore of Long Island, in New York, United States.

The Incorporated Village of Manorhaven is located on the Cow Neck Peninsula, within the Town of North Hempstead.

[3] Between 1939 and 1940, Manhasset Bay was used as the New York base of Pan American World Airways' transatlantic Boeing 314 flights, prior to the opening of LaGuardia Airport's Marine Air Terminal, with the airport's hangars and terminal located within Manorhaven, at Toms Point on Manhasset Isle, near the southern edge of the village; the facility was subsequently used by Grumman, following the Marine Air Terminal's opening.

[14] In 1984, Manorhaven residents and officials again debated whether the village should join the Port Washington Police District.

[15][16] Proponents felt that the Port Washington Police District would be able to better serve the needs of the village, while opponents expressed concerns over potential tax increases.

[17] on June 20, 2023, the village's former Deputy Mayor Vincent Costa was defeated by one vote, after being accused of official misconduct.

[21] Additionally, Port Washington North is located on the northern half of the Cow Neck Peninsula.

[27][28] According to the United States Environmental Protection Agency and the United States Geological Survey, the highest point in Manorhaven is located at the northeastern corner of the village, at approximately 90 feet (27 m), and the lowest point is Manhasset Bay, which is at sea level.

[38][41] Port Washington North is located in New York's 3rd congressional district, which as of July 2024 is represented by Thomas R. Suozzi (D–Glen Cove).

[38][42] Like the rest of New York, Manorhaven is represented in the United States Senate by Charles E. Schumer (D) and Kirsten Gillibrand (D).

[44][45][46] The Village of Manorhaven is located entirely within the boundaries of the Port Washington Union Free School District.

[25] Manhasset Avenue in the southern part of the village is a notable exception, as it traverses the grid diagonally.

[25] Many streets use street-naming conventions of local Native American tribes and places (i.e.: Mohegan Avenue) and of woods (i.e.: Cottonwood Road).

[49][50][52] Manorhaven maintains a village sanitary sewer system, which, through a contract, has its sewage transferred to – and treated by – the Port Washington Water Pollution Control District.

[38][55] The Village of Manorhaven, in its entirety, is located within the boundaries of (and is thus served by) the Port Washington Fire District.
