William S. Key Correctional Center is a facility that is operated by the Oklahoma State Department of Corrections and Community Supervision. It is a maximum security prison for men and houses over 1087 inmates. The facility is located in Fort Supply, Oklahoma, and the prison can get extremely cold, leading to the facility earning the nickname “Oklahoma’s Little Siberia” due to the isolation of Fort Supply and the climate. It is the third oldest prison in Oklahoma, and there are somewhere around 1000 guards at the facility. It is also the largest maximum security prison in the state.

The facility also housed the Oklahoma state death row male inmates up until 2008, as well. The prison was actually built in 1844, and was created so that prisoners can supply labor to local mines. In 1899, a mental health hospital was built on the premises as well, called the Fort Supply State Hospital. The hospital was meant to serve those who were going insane during their sentences.

There are many various well-known individuals that have served time at William S. Key Correctional Center. There is also a garment shop at the facility, as well.

In addition, two individuals escaped from William S. Key Correctional Center in 2015. This became the subject of a show, “Escape from Fort Supply”. The seven-episode series premiered in 2018, and has won various awards.
