Pennsylvania's first congressional district includes all ofBucks County and a sliver ofMontgomery County in southeasternPennsylvania. It has been represented byBrian Fitzpatrick since 2019.

The state congressional district map was redrawn by theSupreme Court of Pennsylvania in February 2018 after ruling the previous map unconstitutional due to partisangerrymandering; the previous 1st district was geographically succeeded by the newly redrawn2nd district which on November 6, 2018, electedBrendan Boyle, the incumbent from the13th district. The new first district is similar to the previouseighth district, with the new boundaries going into effect for the 2018 elections and representation thereafter.^[4] It is the wealthiest congressional district in the state ofPennsylvania.^[5]

Fitzpatrick, the incumbent from the previous 8th district, was elected on November 6, 2018, to the newly redrawn 1st district. Prior to 2018, the district had generally been based in Philadelphia. Only minor changes were made to the district after redistricting following the2020 census.

The district was one of three congressional districts that voted forKamala Harris in the2024 presidential election while simultaneously electing a Republican in theconcurrent House of Representatives elections.^[6]
