How many state prisons are in Maine?

Maine has 6 adult correctional facilities operated by Maine Department of Corrections. Jail411 verified the operating-institution source on August 12, 2026.

Why do sources report different prison counts for Maine?

Facility inventories count every prison-type site as its own row, including camps, annexes, federal facilities and community corrections. A state corrections agency counts only the institutions it operates, under its own definition. For Maine those two methods give 9 and 6. Jail411 publishes Maine Department of Corrections's figure as the answer and shows the directory total separately.

How many county and local jails are in Maine?

Maine has 15 local jail facilities according to Maine Department of Public Safety, Maine Criminal Justice Academy, with the inventory dated December 31, 2025.

Maine has 6 state prisons operated by Maine Department of Corrections, plus 15 county and local jails. This directory lists 9 because it still carries institutions the agency is closing. How we count.

Where are they right now? Jails and prisons are not two separate worlds. They are points on one path, and searching the wrong one is why a name comes back with nothing.

ArrestedTaken to the county jail for the county where the arrest happened — not where they live.
County jailHeld here while the case runs. 16 local jail facilities in Maine. Bail is set and posted here.
Court and sentencingMost people leave from here. Only a sentence to state time moves someone into the prison system.
Released, fined, or a county sentence — the path ends here for most people
Reception centreWeeks, not days. They are scored, assessed and assigned. Expect little contact during this stage — this is the part families are least warned about.
InstitutionPlaced at one of 6 institutions, at a security level set by their score — not by the worst thing the prison is allowed to hold.
Release and supervisionThey report to a parole or probation office, which is rarely the city they were held in.

Where in Maine?

Most people know the county or the city, not the name of the facility. Start there. Bail is set and posted at the county jail, so the county page is also where the sheriff, the custody search and the court contacts live.
