In 1946, Long Island State Park Commission President Robert Moses created the Long Island State Park Police Department to patrol Long Island’s parks.
Throughout its existence, the force was strongly identified with Moses, the so-called "master builder," and provided his chauffeurs and bodyguards.
In 1950, the name of the agency was changed to the Long Island State Parkway Police to reflect its added responsibility of patrolling the parkways in addition to the parks.
Headquartered at Belmont Lake State Park in North Babylon, the New York State Park Police currently patrols 25,000 acres (101 km2) of parkland in Nassau and Suffolk Counties.
