Map of Upper Manhattan, with Harlem and its subsections highlighted
Harlem is located in Upper Manhattan, often referred to as Uptown by locals. It stretches from the Harlem River and East River in the east, to the Hudson River to the west; and between 155th Street in the north, where it meets Washington Heights, and an uneven boundary along the south that runs along 96th Street east of Fifth Avenue, 110th Street between Fifth Avenue to Morningside Park, and 125th Street west of Morningside Park to the Hudson River.
Central Harlem is bounded by Fifth Avenue on the east, Central Park on the south, Morningside Park, St. Nicholas Avenue and Edgecombe Avenue on the west, and the Harlem River on the north. A chain of three large linear parks—Morningside Park, St. Nicholas Park and Jackie Robinson Park—are situated on steeply rising banks and form most of the district's western boundary. On the east, Fifth Avenue and Marcus Garvey Park, also known as Mount Morris Park, separate this area from East Harlem. The bulk of the area falls under Manhattan Community Board No. 10. In the late 2000s, South Harlem, emerged from area redevelopment, running along Frederick Douglass Boulevard from West 110th to West 138th Streets.
The West Harlem neighborhoods of Manhattanville and Hamilton Heights comprise part of Manhattan Community Board No. 9. The two neighborhoods' area is bounded by Cathedral Parkway (110th Street) on the South; 155th Street on the North; Manhattan/Morningside Ave/St. Nicholas/Bradhurst/Edgecome Avenues on the East; and Riverside Park/the Hudson River on the west. Manhattanville begins at roughly 123rd Street and extends northward to 135th Street. The northern most section of West Harlem is Hamilton Heights.
East Harlem, also called Spanish Harlem or El Barrio, within Manhattan Community Board 11, is bounded by East 96th Street on the south, East 138th Street on the north, Fifth Avenue on the west, and the Harlem River on the east.
