Prisoners’ Legal Services is a not-for-profit legal services corporation, founded in 1972, that provides civil legal assistance to people who are incarcerated in Massachusetts state prisons (Department of Correction facilities) or in the county jails and houses of correction.

Prisoners’ Legal Services promotes the safe, humane and lawful treatment of Massachusetts prisoners through civil rights litigation, administrative advocacy, client counseling, and outreach to policy makers and the public.

The office focuses on four issues: health and mental health care, guard-on-prisoner violence, physical conditions of confinement, and segregation and isolation.
