The Staten Island Greenbelt is a system of contiguous public parkland and natural areas in the central hills of the New York City borough of Staten Island. It is the second largest component of the parks owned by the government of New York City and is maintained by the city's Department of Parks and Recreation and the Greenbelt Conservancy, a not-for-profit organization that works in partnership with NYC Parks to care for the Greenbelt and raise funds for its maintenance and programs. The Greenbelt includes High Rock Park, LaTourette Park, William T. Davis Wildlife Refuge, and Willowbrook Park among others.

The New York City Department of Parks and Recreation, also called the Parks Department or NYC Parks, is the department of the government of New York City responsible for maintaining the city's parks system, preserving and maintaining the ecological diversity of the city's natural areas, and furnishing recreational opportunities for city's residents and visitors.
