Franklin is a town in New London County, Connecticut, United States. The town is part of the Southeastern Connecticut Planning Region. The population was 1,863 at the 2020 census. The town includes the village of North Franklin.

Europeans first settled in what would become Franklin in 1663 as part of the larger division of the town of Norwich, Connecticut. The residents of what would become Franklin first petitioned for an ecclesiastical society in 1710, but were denied. Six years later, their petition was granted and they formed the second ecclesiastical society of Norwich, also called the West Farms .

During the First Great Awakening the society was shaken by controversy, partly over the location of the meetinghouse, but mostly fueled by conflict between the Old and New Lights in the society. The minister, Henry Willes, retired in 1749 as a result and in 1758 permission was granted to the eastern portion of the society to be formed as the Eighth, or Pautipaug, society of Norwich.The boundaries between the two societies would not be set until 1761.

The West Farms and Pautipaug societies were incorporated together as the Town of Franklin in 1786. The town is named after Benjamin Franklin.

Until 1861 the town's borders extended east to the Shetucket River and included the early village of Baltic, Connecticut. That year, the town of Sprague, Connecticut, was incorporated from the towns of Franklin and Lisbon, Connecticut, which gave Franklin its present bounds.

According to the United States Census Bureau, the town has a total area of 19.6 square miles (51 km), of which 19.5 square miles (51 km) is land and 0.1 square miles (0.26 km), or 0.36%, is water.
