Oklahoma State Penitentiary is a male maximum-security prison in McAlester. The facility has five housing units - one for death row inmates, two for medium-security inmates and two for general population.
Built in 1908, OSP is the oldest prison in Oklahoma. Its first structure included temporary housing for the inmates who were building the facility, the first of whom arrived in 1909.
The first buildings were the West Cellhouse and Administration Building. A rotunda and East Cellhouse were built later, as well as F Cellhouse. A Special Care Unit opened in 1992.
Most inmates lack education, a key component in avoiding re-incarceration. OSP offers literacy courses as well as Pre-High School Equivalency and High School Equivalency diplomas.
OSP offers Thinking for a Change, Moral Reconation Therapy, and Associates 4 Success programs to address thinking, judgment errors, and relationships linked with criminal thinking/behavior.
OSP is home to Oklahoma’s death row unit for male inmates.
It features a 24-7 infirmary, which provides medical care for inmates who need intensive monitoring and treatment.
OSP also offers the Step-Down Program for newly arrived, maximum-security inmates who would like to earn their way to a lower security level. Its programming addresses criminal thinking and encourages pro-social behaviors.
Inmates can receive mail at any time. Include their name, DOC number and housing assignment if known in the address.
