Marcus Garvey Park is a 20.16-acre park on the border between the Harlem and East Harlem neighborhoods of Manhattan, New York City. The park, centered on a massive and steep outcropping of schist, interrupts the flow of Fifth Avenue traffic, which is routed around the park via Mount Morris Park West. The park is also bounded by 120th Street to the south, 124th Street to the north, and Madison Avenue to the east.
