The Belt Parkway is the name given to a series of controlled-access parkways that form a belt-like circle around the New York City boroughs of Brooklyn and Queens. The Belt Parkway comprises three of the four parkways in what is known as the Belt System: the Shore Parkway, the Southern Parkway, and the Laurelton Parkway. The three parkways in the Belt Parkway are a combined 25.29 miles (40.70 km) in length. The Cross Island Parkway makes up the fourth parkway in the system, but is signed separately.

The majority of parkways in the US state of New York are part of a statewide parkway system owned by several public and private agencies but mostly maintained by the New York State Department of Transportation (NYSDOT). A handful of other roads in the Hudson Valley and on Long Island are also known as parkways but are not part of the state system. The roads of the state parkway system were among the first expressways to be constructed. These highways were not divided and allowed no driveway cuts, but did have intersections for some of the streets they crossed. A small section of the privately financed Long Island Motor Parkway was the first expressway to begin operation as a toll road and the first highway to use bridges and overpasses to eliminate intersections.
