Flatbush is a neighborhood in the New York City borough of Brooklyn. The neighborhood consists of several subsections in central Brooklyn and is generally bounded by Prospect Park to the north, East Flatbush to the east, Midwood to the south, and Kensington and Parkville to the west. The modern neighborhood includes or borders several institutions of note, including Brooklyn College.

The area was home to the Canarsee people before contact with Europeans; many of the tribe’s paths would become important roads through the region. Flatbush was originally chartered as the Dutch Nieuw Nederland colony town of Midwout, also called Vlachte Bos. It was one of the six original European towns on Long Island. The town remained primarily Dutch and rural in character until the latter half of the 19th century, when increasing rail and road connectivity to other parts of New York made it an attractive suburb to Brooklyn and New York City. The town was consolidated into the City of Greater New York in 1898 and was further connected to the rest of the city with the development of the New York City Subway in the early 20th century. Post-World War II, the neighborhood underwent tremendous demographic shifts, becoming home to increasing numbers of immigrants from the Caribbean, Asia, and elsewhere. In the late 20th century and 21st century it has continued to see changes due to gentrification and new immigrants.

Flatbush is part of Brooklyn Community District 14. It is patrolled by the 67th and 70th Precincts of the New York City Police Department. Politically, Flatbush is represented by the New York City Council’s 40th and 45th Districts.
