This is a list of state prisons in Idaho. There are no federal prisons in Idaho and this list does not include county jails located in the state of Idaho.
This template pertains only to agencies that handle sentenced felons (with sentences over 1-2 years). In many states, pre-trial detainees, persons convicted of misdemeanors, and felons sentenced under state law to less than one year are held in county jails instead of state prisons.
