Connecticut county map

Connecticut has eight counties, but none of them has a government. County lines survive on maps, in court districts and in the Census, while the state and its 169 towns provide all local services.

Counties without governments

Connecticut abolished county government on 1 October 1960. Until then each county had a sheriff, a jail and a small board of commissioners, but almost every function — schools, roads, police, welfare, zoning — had always belonged to the towns. Today the eight counties are geographic labels: they still define the boundaries of the state’s judicial districts and appear on every Census table, and the former county seats listed in the table are simply the towns where the old courthouses stood. The sheriffs themselves were replaced by state marshals in 2000.

Because the counties are only lines, the Census Bureau agreed in 2022 to treat Connecticut’s nine regional councils of governments (COGs) as its county-equivalents for statistics from the 2022 releases onward: Capitol Region, Greater Bridgeport, Lower Connecticut River Valley, Naugatuck Valley, Northeastern Connecticut, Northwest Hills, South Central Connecticut, Southeastern Connecticut and Western Connecticut. The 2020 Census figures used on this site still refer to the eight counties.

The four original counties — Fairfield, Hartford, New Haven and New London — were created together in 1666, making them among the oldest in the United States. Windham (1726), Litchfield (1751), Middlesex and Tolland (both 1785) were split from them.

Five county facts

Reading the map

Press Streets and zoom in to see the county lines, which mostly follow town boundaries rather than rivers. Hartford County straddles the Connecticut River in the centre of the state; Middlesex and New London share the river’s mouth on Long Island Sound; Fairfield and New Haven make up the Sound’s western shore. Litchfield in the north-west and Windham and Tolland in the north-east are the hill counties. Bridgeport, the largest city, is in Fairfield County; the capital Hartford is in Hartford County. The whole state is on Eastern Time.
