Lebanon is a town in New London County, Connecticut, United States. The population was 7,308 at the 2010 census. The town lies just to the northwest of Norwich, directly south of Willimantic, 20 miles (32km) north of New London, and 20 miles (32km) east of Hartford. The farming town is best known for its role in the American Revolution, where it was a major base of American operations, and for its historic town green, which is one of the largest in the nation and the only one still used partially for agriculture. Lebanon was originally settled by the Moheganpeople, an Algonquian-speaking tribe that inhabited the upper Thames River Valley in eastern Connecticut. The area was known as Poquechaneed and was used primarily for hunting.
