Pennsylvania's 12th congressional district is located in southwestern Pennsylvania, including Pittsburgh and much of Allegheny County, as well as some of Westmoreland County. Since January 3, 2023, it has been represented by Summer Lee.
Before 2018, the 12th district was located in southwestern Pennsylvania and included all of Beaver County, and parts of Allegheny, Cambria, Lawrence, Somerset, and Westmoreland Counties. The Supreme Court of Pennsylvania redrew this and other state congressional districts in February 2018 after ruling the previous map unconstitutional due to partisan gerrymandering. The new 12th district covers much of the old 10th district. The old 12th district was redrawn to an area north and west of Pittsburgh and renamed the 17th district for the 2018 elections and representation after that.[2]
Before the 2011 round of redistricting, the 12th district was widely considered to be gerrymandered by the Republican-controlled state legislature as a heavily Democratic district. It consisted of all of Greene County, and parts of Allegheny, Armstrong, Cambria, Fayette, Indiana, Somerset, Washington, and Westmoreland Counties.
