The Cumberland County Jail is located in Portland, Maine, and is the largest jail in the state. The jail, a division of the Cumberland County Sheriff's Office, is a part of Cumberland County government and is wholly operated by the elected Sheriff. In 2002 it became the first jail in the state of Maine to receive national accreditation from the American Correctional Association, at the time putting it among only 4% of adult correctional facilities in the USA to have been so accredited.
