Middletown

Middletown is a city in Middlesex County, Connecticut, United States. Located along the Connecticut River, in the central part of the state, it is 16 miles south of Hartford. Middletown is the largest city in the Lower Connecticut River Valley Planning Region. In 1650, it was incorporated by English settlers as a town under its original Native American name, Mattabeseck, after the local indigenous people, also known as the Mattabesett. They were among the many tribes along the Atlantic coast who spoke Algonquian languages. The colonists renamed the settlement in 1653.

When Hartford County was organized on May 10, 1666, Middletown was included within its boundaries. In 1784, the central settlement was incorporated as a city distinct from the town. Both were included within newly formed Middlesex County in May 1785. In 1923, the City of Middletown was consolidated with the Town, making the city limits extensive.
