Upper Manhattan denotes the more northerly region of the New York City Borough of Manhattan. Its southern boundary may be defined anywhere between 59th Street and 155th Street. Between these two extremes lies the most common definitions of Upper Manhattan as Manhattan above 96th Street (the southern boundary of Manhattan Valley in the west and Spanish Harlem in the east) . This definition of Upper Manhattan takes in the neighborhoods of Marble Hill, Inwood, Washington Heights (including Fort George, Sherman Creek and Hudson Heights), Harlem (including Sugar Hill and Hamilton Heights), and parts of the Upper West Side (Morningside Heights and Manhattan Valley).
In the late 19th century, the IRT Ninth Avenue Line and other elevated railroads brought urban sprawl to the previously rustic Upper Manhattan. Until the late 20th century it was less influenced by the gentrification that had taken place in other parts of New York over the previous 30 years.
