Enfield was a town in Hampshire County, Massachusetts, United States.

At the town's final ball, the band played Auld Lang Syne.

The headquarters of the Metropolitan District Commission during the construction of the Quabbin Reservoir was located in the former town hall, and was the last building razed in the Swift River Valley, in 1940.

The majority of the town center now lies submerged beneath the reservoir, although the Quabbin Observatory and Enfield Lookout, located on scenic Quabbin Hill, as well as the main entrance and headquarters of Quabbin State Park, a popular tourist destination with an emphasis on state history and nature, are all within the former town's limits.

Enfield House, an on-campus living facility at Hampshire College in Amherst, Massachusetts, is named after the former town.
