Sister cities of Great Neck, New York

Great Neck is a region on Long Island that covers a peninsula on the North Shore of Long Island, which includes the villages of Great Neck, Great Neck Estates, Great Neck Plaza, and others, as well as an area south of the peninsula near Lake Success and the border territory of Queens. The incorporated village of Great Neck had a population of 9,989 at the 2010 census, while the larger Great Neck area comprises a residential community of some 40,000 people in nine villages and hamlets in the town of North Hempstead, of which Great Neck is the northwestern quadrant. Great Neck has five postal zones (11020–11024) and one school district.

The hamlets are census-designated places that consolidate various unincorporated areas. They are statistical entities and are not recognized locally. However, there are locally recognized Harbor Hills, Saddle Rock Estates, University Gardens, and Manhasset neighborhoods within the hamlet areas. The Manhasset neighborhood (in zip code 11030) is not considered part of Great Neck. The part of the Hamlet of Manhasset that is considered part of Great Neck includes the Great Neck Manor neighborhood. Great Neck Gardens is featured on many maps as a name of one such hamlet, even as the name is used rarely if ever by local residents.

Great Neck is a 25- to 35-minute commute from Manhattan's Penn Station on the Port Washington Branch of the Long Island Rail Road via the Great Neck station, which is one of the most frequently served in the entire system. Nassau Inter-County Express connects the villages to the train station and offers service to several destinations in Nassau County and Queens from the station, while the southern part of the Great Neck area can also directly access the Q46 New York City Bus on Union Turnpike at the border with Glen Oaks and the Q12 bus on Northern Boulevard at the border with Little Neck.
