Charlemont is a town in Franklin County, Massachusetts, United States. It is part of the Springfield, Massachusetts Metropolitan Statistical Area. Charlemont was first settled in 1743, having been set off as Boston Township Number 1 in 1735. The town was along the distant frontier at the time, and was the subject of several raids by Native Americans. The town was incorporated as Charlemont in 1765, most likely named for the town in Northern Ireland. The town was mostly rural, with farming being the main industry until the advent of the railroad, which traveled through town towards the Hoosac Tunnel. Today the town industry also includes tourism, with a ski area and other tourist areas along the Mohawk Trail.
