Morningside Heights is a neighborhood of the borough of Manhattan in New York City, on the border of the Upper West Side and west Harlem. The area is usually described as being on the Upper West Side, but has been described as part of "Greater Harlem" due to a disputed claim that the Upper West Side goes no further north than 110th Street.

Morningside Heights is bounded by Morningside Park at Morningside Drive to the east, Manhattanville and Harlem at 125th Street to the north, Manhattan Valley at 110th Street to the south, and Riverside Park at Riverside Drive to the west.The main thoroughfare is Broadway. 

It is chiefly known as the home of institutions such as Columbia University, Teachers College, Barnard College, the Manhattan School of Music, Bank Street College of Education, "Grant's Tomb", Jewish Theological Seminary of America, and Interchurch Center. However, Morningside Heights also contains the Cathedral of Saint John the Divine, the Riverside Church, the Broadway Presbyterian Church, Union Theological Seminary in the City of New York, and St. Luke's Hospital. The neighborhood is part of New York's 13th congressional district, which includes all of Upper Manhattan since 2013.[11]
