Connecticut has five congressional districts, each sending one member to the U.S. House of Representatives. The current boundaries were adopted by the Connecticut Supreme Court on February 10, 2022, after the 2020 Census, and all five seats are currently held by Democrats who won reelection in November 2024.
How the Five Districts Are Laid Out
Connecticut has held five U.S. House seats since the 2000 Census.1Britannica. United States House of Representatives Seats by State Together the districts cover every square mile of the state. In most cases whole towns sit inside a single district, so knowing your town is usually enough to know your representative. A small number of municipalities are split between two districts, and in those places the specific address decides.
The 2022 map moved only about 71,700 residents into new districts, the minimum needed to equalize population, and it touched just four municipalities that were already split. Most residents saw no change in representation.
1st District: Hartford and North-Central Connecticut
The 1st District covers 27 cities and towns across Hartford, Litchfield, and Middlesex Counties, with a population of roughly 700,000.2Congressman John Larson.

2nd District: Eastern Connecticut
The 2nd District covers roughly the eastern third of the state, running from the Long Island Sound shoreline north to the Massachusetts border. It includes all of New London, Tolland, and Windham Counties, plus parts of Middlesex and Hartford Counties. Norwich, New London, Groton (home to the Naval Submarine Base), and Enfield are the major population centers. The southern shoreline gives way to the rural “Quiet Corner” in the northeast.

3rd District: New Haven and the South-Central Coast
The 3rd District is anchored by New Haven, home to Yale University, and takes in much of New Haven County along the south-central coast, including Milford and Stratford, part of Middletown, and stretches of the Naugatuck Valley.

4th District: Fairfield County and the Gold Coast
The 4th District covers most of Fairfield County in the southwestern corner of the state, an area often called the Gold Coast. It runs from Greenwich on the New York border northeast through Stamford, Norwalk, and Fairfield to Bridgeport, still the state’s largest city by population.

Finding Your District
The Connecticut General Assembly maintains a lookup tool at cga.ct.gov that lists every town alongside its congressional district, state senate district, and state house district.4Connecticut General Assembly. Connecticut Congressional Representation The U.S. House also offers an address-based lookup at house.gov, which is the tool to use if your town is one of the ones split between two districts.
Voting for Your Representative
House members serve two-year terms, so every district votes on its representative every even-numbered November. To cast a ballot, you need to be registered in Connecticut. The standard deadline is 18 days before Election Day.5State of Connecticut. Voter Registration Information If you miss it, Connecticut offers same-day registration at a designated location in your town on Election Day. You can register online, by mail, or at your local town clerk’s office, and federal law also lets you register when applying for or renewing a driver’s license at the DMV.
How the Map Gets Drawn
Boundaries are redrawn every ten years after the federal census to keep populations equal across the five districts. Article III, Section 6 of the state constitution sets the process out in stages.6Connecticut General Assembly. Connecticut Constitution Article 3, Section 6 The General Assembly acts first, needing a two-thirds vote in each chamber; the governor has no veto over redistricting. If the legislature misses its September 15 deadline the year after the census, a nine-member bipartisan Reapportionment Commission takes over, with a November 30 deadline of its own. If the commission also fails, the Connecticut Supreme Court has original jurisdiction and can draw the map itself.7Connecticut General Assembly. Connecticut’s Redistricting Procedures and Deadlines
That last step is what produced the current map. After the 2020 Census the commission deadlocked, and the Supreme Court appointed a special master whose plan the court adopted in February 2022. Any plan must satisfy the federal “one person, one vote” standard, which requires congressional districts to be as close to mathematically equal in population as practicable, with any deviation justified by a legitimate state objective.
