Deerfield employs the open town meeting form of government and is led by a board of selectmen. The town has its own police, fire, and public works departments. The fire department and the post office both have two branches, in South Deerfield (where most of the town offices are) and in Old Deerfield Village, near Memorial Hall and the Old Town Hall. The town's Tilton Library is connected to the regional library network and is located in South Deerfield. The nearest hospital, Franklin Medical Center, is located in Greenfield, as are many regional state offices.
