Connecticut's 3rd congressional district is acongressional district in theU.S. state ofConnecticut. Located in the central part of the state, the district includes the city ofNew Haven and its surrounding suburbs.

Principal cities include:Middletown,New Haven, andStratford.

The district is currently represented byDemocratRosa DeLauro.

The 3rd congressional district has existed since 1837, having been organized from the at-large congressional district. It is centered onNew Haven and its suburbs. The district comprises four-fifths ofNew Haven County, a small portion ofMiddlesex County, including most ofMiddletown, and most ofStratford and a small section ofShelton inFairfield County.

New Haven and its surrounding suburbs are largely Democratic, making the district very Democratic in local and federal elections. Among districts statewide, only the1st congressional district is considered more Democratic. Four Democratic strongholds,New Haven,Hamden,Middletown, andWest Haven, comprise 40% of the total district population. Since 2000, Democratic presidential candidates have carried the district by a margin of 26 points.John Kerry, being the exception, still defeatedGeorge W. Bush by a comfortable 14 points. On the state level, moderate RepublicansJohn G. Rowland andM. Jodi Rell have also carried the district.

Since 1933, Democrats have held the district for all but six terms (1943–45, 1947–49, 1953–59, 1981–83). Between 1972-1988, every Republican nominee for President carried the district, along with the state itself. In his sole run for a House seat,Joe Lieberman, lost the district to a Republican in 1980.

For the118th and successive Congresses (based on redistricting following the2020 census), Connecticut's 3rd district contains portions of four planning regions and 25 municipalities.^[3]
