Souza-Baranowski Correctional Center (SBCC) is a maximum security prison in Lancaster, Massachusetts (though it receives mail through a post-office box in the town of Shirley).

It is close to the medium-security prison Massachusetts Correctional Institution – Shirley, which is directly to the north over the town border.

The complaints included unprovoked beatings and use of stun guns, positional torture, ripping out of hair, underfeeding, confiscation of all clothing, deprivation of personal property, denial of access to lawyers and legal paperwork, failure to follow procedure by videotaping raids and documenting injuries, and use of personnel from other facilities who hid their identities.
