Middlesex County is a county located in the south central part of the U.S. state of Connecticut. It was created in May 1785 from portions of Hartford and New London counties. As of 2010, the population was 165,676.
As is the case 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 fire and rescue, snow removal, and schools. In a few cases, neighboring towns will share certain resources, e.g. water, gas, etc. Middlesex County is merely a group of towns on a map, and no longer has any particular authority.
