The Chesapeake Detention Facility (CDF), previously the Maryland Correctional Adjustment Center (MCAC), is a maximum level II (supermax or control unit) prison operated by the Maryland Department of Public Safety and Correctional Services in Baltimore.

It was built in 1988, and is located at 401 East Madison Street in Baltimore, Maryland, United States.

Federal detainees recreate together both inside and outside every day of the week, eat together, and have access to phones.

Until June 2010, CDF also housed Maryland's death row inmates.

Executions took place across the street from the MCAC at the former Maryland Penitentiary (now known as the Metropolitan Transition Center).
