Cimarron Correctional Facility is a medium security prison in unincorporated Payne County, Oklahoma,[1] located 3 miles (4.8 km) southwest of the city of Cushing.

It is owned and operated by CoreCivic, formerly Corrections Corporation of America, under contract with the United States Marshals Service.

In March 2012, the Puerto Rico Department of Corrections and Rehabilitation agreed to send as many as 480 inmates to Cimarron, to alleviate overcrowded prisons on the island.

[4] The three-year contract was ended prematurely in June 2013 after unit-wide fights and "disruptive events", and the inmates were sent back to Puerto Rico.

Due to reductions by the Oklahoma Department of Corrections in the number of inmates put in private prisons because of budgetary issues, CoreCivic announced closure of the facility in July 2020.
