The Cross Island Parkway is a controlled-access parkway in New York City and Nassau County, part of the Belt System of parkways running along the perimeter of the boroughs of Queens and Brooklyn. The Cross Island Parkway runs 10.6 miles (17.1 km) from the Whitestone Expressway in Whitestone past the Throgs Neck Bridge, along and across the border of Queens and Nassau County to meet up with the Southern State Parkway, acting as a sort of separation point which designates the limits of New York City. The road is designated as New York State Route 907A (NY 907A), an unsigned reference route, and bears the honorary name 100th Infantry Division Parkway.

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.
