Connecticut's 5th congressional district is acongressional district in theU.S. state ofConnecticut. Located in the western part of the state and spanning across parts ofFairfield,Litchfield,New Haven, andHartford Counties, the district runs fromMeriden andNew Britain in central Connecticut, westward toDanbury and the surroundingHousatonic Valley, encompassing theFarmington Valley,Upper Naugatuck River Valley, and theLitchfield Hills. The district also includes most ofWaterbury.^[3]

The district is currently represented byDemocratJahana Hayes. With aCook Partisan Voting Index rating of D+3, it is the least Democratic district in Connecticut, a state with an all-Democratic congressional delegation.^[2]

In the early 20th century, the 5th congressional district included Waterbury, Litchfield County, and the Naugatuck Valley. It did not include any portion of Fairfield or Hartford counties and did not include theCity of Meriden.

From 1964 to 1990, the 5th congressional district included many towns inFairfield County which are now located in the 4th congressional district, such asWilton,Monroe,Ridgefield, andShelton. It also included the lowerNaugatuck River Valley towns ofAnsonia,Derby,Seymour, andNaugatuck which are now in the 3rd congressional district.

The current 5th congressional district was created in 2002 due toreapportionment following the2000 U.S. census. Due to slow population growth, Connecticut lost a seat and the oldWaterbury-based 5th district was merged with the New Britain-based6th district. However, the merged district contained more of the old 6th's territory.

Although historically Republican, the 5th congressional district has been trending Democratic since 2004.John Kerry carried the district with 49.3% of the vote, a margin of 1,112 votes in the2004 presidential election.Barack Obama carried the district in 2008 with 56.3% of the vote and in 2012 with 53.5% of the vote.

For the118th and successive Congresses (based on redistricting following the2020 census), Connecticut's 5th district contains portions of four planning regions and 40 municipalities.^[4]
