Pennsylvania's 17th congressional district is located in southwestern Pennsylvania, which includes the entirety of Beaver County and the northwestern parts of Allegheny County not part of the 12th district. It has been represented since January 3, 2023 by Democrat Chris Deluzio.

In January 2018, the Supreme Court of Pennsylvania ruled that the 2011 map violated the state constitution and redrew it on February 18, 2018. What was the 17th district, which had been anchored in Northeast Pennsylvania, was modified to become the 9th district, and the old 12th district likewise became the 17th, for the 2018 elections and representation thereafter until the current map was ordered on February 23, 2022.^[3][4][5] In the 2020 redistricting cycle, its portion of Butler County, including Cranberry Township, was removed from the district, while it gained some eastern suburbs of Pittsburgh, such as Forest Hills and Wilkinsburg.

The district is one of seven with a Cook Partisan Voting Index of EVEN, meaning that the district votes almost identically to the national electorate. Pennsylvania has two of these districts; the other one is the 1st district.
