Middlesex County is a county in the south central part of the U.S. state of Connecticut. As of the 2020 census, the population was 164,245. The county was created in May 1785 from portions of Hartford County and New London County.

Middlesex County is included in the Hartford-East Hartford-Middletown metropolitan statistical area known as Greater Hartford.

As with all eight of Connecticut's counties, there is now no county government and no county seat. In Connecticut, towns are responsible for all local government activities, including local police, fire and rescue, snow removal, and schools. In a few cases, neighboring towns will share certain resources, e.g. water, gas, etc. On June 6, 2022, the U.S. Census Bureau formally recognized Connecticut's nine councils of governments as county equivalents instead of the state's eight counties. Connecticut's county governments were disbanded in 1960, and the councils of governments took over some of the local governmental functions. Connecticut's eight historical counties continue to exist in name only, and are no longer considered for statistical purposes.https://www.federalregister.gov/documents/2022/06/06/2022-12063/change-to-county-equivalents-in-the-state-of-connecticut Federal Register: Change to County-Equivalents in the State of Connecticut

Government

Middletown was the county seat of Middlesex County from its creation in 1785 until the elimination of county government in 1960. There is no government in Middlesex County other than the Middlesex County Judicial District. All county functions other than courts and county sheriff's departments were discontinued in 1960, and again in 2000 when the county sheriff's departments were reorganized as the Connecticut Judicial Marshal, due to political corruption in the county sheriff's departments. Joseph E. Bibisi was the last person to serve as high sheriff of Middlesex County.
