Park Avenue is a wide New York City boulevard which carries north and southbound traffic in the borough of Manhattan, and is also a wide one-way pair in the Bronx. For most of the road's length in Manhattan, it runs parallel to Madison Avenue to the west and Lexington Avenue to the east. Park Avenue's entire length was formerly called Fourth Avenue; the title still applies to the section between the Bowery and 14th Street. Meanwhile, the section between 14th and 17th Street is called Union Square East, and between 17th and 32nd Streets, the name Park Avenue South is used. In the Bronx, Park Avenue runs in several segments between the Major Deegan Expressway and Fordham Road.

Park Avenue was originally known as Fourth Avenue and carried the tracks of the New York and Harlem Railroad starting in the 1830s. The railroad originally ran through an open cut through Murray Hill, which was covered with grates and grass between 34th and 40th Street in the early 1850s. A section of this "park" was later renamed Park Avenue in 1860, which was afterwards applied to the area leading up to 42nd Street. When Grand Central Depot was opened in the 1870s, the railroad tracks between 56th and 93rd Streets were sunk out of sight and, in 1888, Park Avenue was extended to north of Grand Central.
