Fort Devens is a United States Army Reserve military installation in the towns of Ayer and Shirley, in Middlesex County and Harvard in Worcester County in the U.S. state of Massachusetts. Due to extensive environmental contamination it was listed as a superfund site in 1989. Most of the fort's land was sold off in 1996, but the cantonment area of the post was retained by the Army as the Devens Reserve Forces Training Area (RFTA). Fort Devens was reactivated in May 2007, though no units of active Army have been located there. The Devens Range Complex operates on property in Lancaster, south of Route 2, for live-fire training with small arms, machine guns, grenades, and rockets.^[1]

In 2011, the fort had a population of 306 enlisted personnel, 2,151 reservists, 348 civilians, and 1,399 family members, and maintained 25 ranges, 21 training areas, and 15 maneuver areas on nearly 5,000 acres (20 km²) of land. It was home to the United States Army Base Camp Systems Integration Laboratory as well as the United States Army System Integration Laboratory.^[2]

Part of the former area of the military base is now home to Federal Medical Center, Devens, a federal prison for male inmates requiring specialized or long-term medical or mental health care.^[3]
