The Montana State Prison is in Deer Lodge, Montana. The facility is situated in the unincorporated part of Powell County. 

The Montana State Prison was built between the years of 1974 to 1979. The facility was built due to the degeneration of the original prison that was in the downtown area of Deer Lodge. 

The original prison before the Montana State Prison was constructed was known as the “Old Prison”. It was built in 1871. It was Montana’s prison until the Montana State Prison was built in 1979.

Throughout the Montana State Prisons life, the facility always had to deal with insufficient funds, overcrowding, and antiquated facilities. 

The Montana State Prison can house around 1,500 male inmates. The facility holds a variety of security levels. These security levels include the following: 

•    Minimum I
•    Minimum II
•    Medium I
•    Medium II
•    Maximum 
•    Closed Custody

Inmates will be housed in one of three compounds. Their housing assignment solely depends on what their security level is. 

The facility is surrounded by two fences alongside a large wall topped with razor wire. 

The Montana State Prison also has a re-entry center too. The re-entry center can hold up to 192 inmates. This facility is right outside the fence from the main campus building. The facility is a minimum-security level. Inmates who are in this re-entry center work on the dairy farm and the ranch for the Montana Correctional Enterprise.
