Wyoming Correctional Facility is a medium-security state men's prison in Town of Attica, Wyoming County, New York.^[1] The prison is located adjacent to the better-known maximum security Attica Correctional Facility. The Wyoming prison first opened in 1984. As of 2010 Wyoming had a working capacity of 1722 inmates.^[2]

The Wyoming prison was constructed in response to the notorious Attica Prison riot, which took place in September 1971 at the now adjacent Attica prison, thirteen years prior to the construction of the Wyoming prison. All but four of the 43 men who died in the Attica event, including 10 hostages, were killed by law enforcement gunfire.
