New Hampshire State Prison for Men (NHSP-M)

New Hampshire State Prison For Men is a multi-security state prison for male inmates that is located in Concord, New Hampshire.

The New Hampshire State Prison for Men (NHSP-M) is the state's oldest prison facility. The original state prison was built in 1812. A new facility was constructed in 1878. Following extensive renovations and new construction in the 1980s, this facility remains in use today. The NHSP-M is a multi-security level, male-only facility with an operational capacity of 1,408.

The majority of individuals housed at the NHSP-M are in one of the three general population housing units. The NHSP-M also includes two separate housing units for higher custody level individuals in our care and custody and the Reception and Diagnostic (R & D) area which houses those newly sentenced, probation or parole violators, and those in short-term protective custody review status.

Throughout SFY 2021 and extending into SFY 2024, a series of Capital Budget improvement projects have been underway to make necessary repairs and updates to different parts of this aged facility. These include the repair and replacement of two elevators, bathroom updates to two of the general population units, the replacement of a facility-wide “man down / body alarm” system, upgrades to the internal video surveillance system, roof replacements, and repair and replacement of several security doors. Design and specification have started on a new central kitchen.
