Interactive map of Middlesex County, Connecticut

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.^[1] 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.^[2]
