Hicksville is a hamlet and census-designated place (CDP) within the Town of Oyster Bay in Nassau County, on Long Island, in New York, United States.

It turned into a bustling New York City suburb in the building boom following World War II.

[6] Many residents felt that by incorporating as a village, the community would be run more effectively than by the Town of Oyster Bay.

[6][7][8] However, these plans were unsuccessful, and Hicksville remains an unincorporated area of the Town of Oyster Bay to this day, as of 2023.

[13] Metalab Equipment Company, a division of Norbute Corp, made laboratory furniture and cabinetry.

RUCO Polymer Corp. (Hooker Chemical Company) manufactured plastics, latex, and esters.

The LIRR removed the switch during track work sometime after the closure and demolition of the buildings on the property.

The LIRR has a team yard on West John Street, just east of Charlotte Avenue, served by the New York and Atlantic Railway, for off-line freight customers receiving or shipping cargo by rail to anywhere in the North American rail network.

[18] Hicksville is home to a number of South Asian grocery stores, clothing shops and restaurants, due to its large proportion of immigrants from India, Pakistan, and Bangladesh.

[22] By 1996 there were around four to five restaurants in Hicksville serving South Asian cuisine, and this started the ascent of a "Little India" there.

[10][25] However, a small part of the hamlet's southeastern corner is located within the boundaries of the Bethpage Union Free School District while a small portion of the hamlet's northeastern corner is located within the boundaries of the Syosset Central School District.
