Rikers Island is the name of New York City's largest jail facility, as well as the name of the 413.17-acre (1.672 kmē) island on which it sits, in the East River between the boroughs of Queens and the Bronx, adjacent to the runways of LaGuardia Airport.

The jail complex, operated by the New York City Department of Correction, has a budget of $860 million a year, a staff of 10,000 officers and 1,500 civilians to control a yearly inmate population of up to 130,000.

The official permanent population of the island, as reported by the United States Census Bureau, was 12,780 as of the 2000 census.

Sing Sing Correctional Facility is a maximum security prison in Ossining, New York. It is located in Westchester County approximately 30 miles north of New York City on the edge of the Hudson River. The name comes from the original name of the village of Ossining, though the penitentiary was first called "Mount Pleasant" when it opened in 1828.

Today Sing Sing houses more than 1,700 prisoners. There are plans to convert the original 1825 cell block, which still stands, into a museum.
