Connecticut is the southernmost state in the New England region of the Northeastern United States. It borders Rhode Island to its east, Massachusetts to its north, New York to its west, and Long Island Sound to its south. Its capital is Hartford, and its most populous city is Bridgeport. Historically, the state is part of New England as well as the tri-state area with New York and New Jersey. The state is named for the Connecticut River which approximately bisects the state. The word Connecticut is derived from various anglicized spellings of Quinnetuket, a Mohegan-Pequot word for "long tidal river". As of the 2020 United States census, Connecticut was home to over 3.6 million residents, its highest decennial count ever, growing every decade since 1790.

In the United States, a county or county equivalent is an administrative or political subdivision of a U.S. state or other territories of the United States which consists of a geographic area with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. The specific governmental powers of counties vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs. Some municipalities have been consolidated with their county government to form consolidated city-counties, or have been legally separated from counties altogether to form independent cities. Conversely, those counties in Connecticut, Rhode Island, eight of Massachusetts's 14 counties, and Alaska's Unorganized Borough have no government power, existing only as geographic distinctions.

From 1666 to 1960, Connecticut had a system of county governments, which each had limited powers given to it by the General Assembly. They were abolished by Public Act 152 in 1960. Connecticut also had a system of sheriffs' offices until October 2000, when those were also abolished.
