Morningside Heights is a neighborhood of the Borough of Manhattan in New York City and is chiefly known as the home of institutions such as Barnard College, Columbia University, the Manhattan School of Music, the Cathedral of Saint John the Divine, the Riverside Church, and St. Luke's Hospital.

Morningside Heights is bounded by the Upper West Side to the south, Morningside Park to the east, Harlem to the north, and Riverside Park to the west. The streets that form its boundaries are 110th Street on the south, Riverside Drive on the west, 125th Street on the north, and Morningside Drive on the east. The main thoroughfare is Broadway. With the recent gentrification of Bloomingdale, the neighborhood immediately to the south of Morningside Heights, the southern boundary of this region is sometimes stretched to 106th Street.

The neighborhood has also been referred to as the "Academic Acropolis," the "Acropolis of New York," "Bloomingdale Village," and, in the words of one comedian, "White Harlem."
