How many counties does Connecticut have?
Connecticut's counties exist on the map but no longer function as units of government — the state eliminated county-level administration in 1960 and replaced it with regional councils of government in 2022. The boundaries are still used by the US Census, the courts, and the state geographic naming system.
The largest county by land area is Capitol County at 0 square miles, home to about 977,746 residents.
At the other end of the scale, Northeastern Connecticut County has only about 94,710 residents.
Connecticut’s capital is Hartford, while the largest city is Bridgeport — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
