Garden City is a village in the town of Hempstead in central Nassau County, New York, in the United States. It was founded by multi-millionaire Alexander Turney Stewart in 1869, and is located on Long Island, to the east of New York City, 18.5 miles (29.8 km) from midtown Manhattan, and just south of the town of North Hempstead. A very small section of the village is in North Hempstead.
As of the 2010 census, the population of the incorporated village was 22,371.
The Garden City name is applied to several other unincorporated, nearby jurisdictions. In the region, hamlets such as Garden City South, Garden City Park and East Garden City are adjacent to the incorporated village of Garden City, but are not themselves part of it. Roosevelt Field, the shopping center built on the former airfield from which Charles Lindbergh took off on his landmark 1927 transatlantic flight, is located in East Garden City.
Adelphi University's main campus is located in Garden City.
