The U.S. state of Connecticut is divided into 169 municipalities, including 19 cities, 149 towns and 1 borough, which are grouped into eight counties.

Towns traditionally have a town meeting form of government; under the Home Rule Act, however, towns are free to choose their own government structure. Nineteen of the towns in Connecticut are consolidated city-towns, and one (Naugatuck) is a consolidated borough-town.

City incorporation requires a Special Act by the Connecticut General Assembly. All cities in Connecticut are dependent municipalities, meaning they are located within and subordinate to a town. However, except for one, all currently existing cities in Connecticut are consolidated with their parent town. Former inner-cities are listed in a separate table below.

Towns in Connecticut are allowed to adopt a city form of government without the need to re-incorporate as an inner-city. Connecticut state law also makes no distinction between a consolidated town/city and a regular town. Bolded city names indicate the state's largest cities, with the most populated being Bridgeport. Currently, Tolland County and Windham County are the only counties in Connecticut without a single city in them.

Note: There are currently 21 cities in Connecticut and those with a population greater than 100,000 are listed in bold.
