Oregon State Penitentiary (OSP), also known as Oregon State Prison, is a maximum security prison in the northwestern United States in Salem, Oregon. Originally opened in Portland 174 years ago in 1851, it relocated to Salem fifteen years later. The 2,242-capacity prison is the oldest in the state; the all-male facility is operated by the Oregon Department of Corrections (ODOC). OSP contains an intensive management wing, which is being transformed into a psychiatric facility for mentally ill prisoners throughout Oregon.
