The first Brooklyn Chinatown, was originally established in the Sunset Park area of the New York City borough of Brooklyn. It is one of the largest and fastest growing ethnic Chinese enclaves outside of Asia, as well as within New York City itself. Because this Chinatown is rapidly evolving into an enclave predominantly of Fuzhou immigrants from Fujian Province in China, it is now increasingly common to refer to it as the Little Fuzhou or Fuzhou Town of the Western Hemisphere; as well as the largest Fuzhou enclave of New York City.

Sunset Park is a neighborhood in the western part of the New York City borough of Brooklyn, bounded by Park Slope and Green-Wood Cemetery to the north, Borough Park to the east, Bay Ridge to the south, and New York Harbor to the west. The neighborhood is named for a public park of the same name that covers 24.5 acres (9.9 ha) between Fifth and Seventh Avenues from 41st to 44th Street. The area north of 36th Street is alternatively known as Greenwood Heights, while the section north of 24th Street is also called South Slope.
