St. Nicholas Avenue is a major street that runs north-south between 193rd Street and 111th Streets in the New York City borough of Manhattan. It goes through the neighborhoods of Harlem, Hamilton Heights, and Washington Heights. St. Nicholas Avenue serves as a border between the West Side of Harlem and Central Harlem. Although Harlem in a broad sense spans from the East River to the Hudson River, the area west of St. Nicholas Avenue is not always counted as part of Harlem proper.
The IND Eighth Avenue Line (A C B D trains) runs under St. Nicholas Avenue north of 121st Street as far as 168th Street, and is sometimes referred to as the St. Nicholas Avenue Line.
North of 169th Street, St. Nicholas Avenue is aligned with the street grid with Wadsworth Avenue one block west (north of 174th Street) and Audubon Avenue. It crosses over the Trans-Manhattan Expressway at 178-179th Streets. The intersection of St. Nicholas with Broadway at 167th Street forms Mitchell Square Park. Below 169th Street, St. Nicholas Avenue cuts at a diagonal to much of the Manhattan street grid, crossing Amsterdam Avenue at 162nd Street and continuing against the grain to West 148th Street. Below 148th, St. Nicholas returns to a rough parallel track, with Convent Avenue one block west and Edgecombe Avenue, down to 124th Street. Below 124th, St. Nicholas Avenue takes a sharp diagonal, crossing Frederick Douglass Boulevard at 121st Street, Adam Clayton Powell Jr. Boulevard at 116th Street, ending at Lenox Avenue, just north of Central Park. Its 17th-century origin as part of Eastern Post Road accounts for its non conformance to the later grid.
