Island Park is a village located in the Town of Hempstead in Nassau County, New York, United States.

Island Park was developed by the Island Park-Long Beach Company as a resort community in the 1920s, after previous development plans for the area were cancelled due to the outbreak of World War I and the subsequent wartime efforts.

[2][3] In the 1950s, there was a proposal in which Island Park would have annexed the adjacent hamlet of Harbor Isle.

[4][5][6] The proposal was ultimately defeated, and to this day, Harbor Isle remains an unincorporated hamlet governed by the Town of Hempstead.

[6][7] According to the United States Census Bureau, the village has a total area of 1.5 square miles (3.9 km2), all land.

Its northern borders follow another channel, while its eastern and southern borders are delineated by the rails of the Long Beach Branch of the Long Island Rail Road.

23.3% of all households were made up of individuals, and 9.6% had someone living alone who was 65 years of age or older.

[11] The board votes on all resolutions in the village and are chiefly responsible for all municipal operations.
