The 2008 congressional elections in Pennsylvania was held on November 4, 2008, to determine who will represent the state of Pennsylvania in the United States House of Representatives. Pennsylvania has 19 seats in the House, apportioned according to the 2000 United States census. Representatives are elected for two-year terms; those elected will serve in the 111th Congress from January 4, 2009, until January 3, 2011. The election coincides with the 2008 U.S. presidential election.

District 3 was the only seat which changed party (from Republican to Democratic), although CQ Politics had forecasted districts 3, 4, 6, 8, 10, 11, 15 and 18 to be at some risk for the incumbent party. This was the last time the Democrats would win a majority of congressional districts in Pennsylvania until 2022.

District 1

Five-term incumbent Bob Brady (D) ran for another term after losing his bid to be mayor of Philadelphia. He was challenged by businessman Mike Muhammad (R). This race was viewed as noncompetitive, as it took place in heavily Democratic Philadelphia. Brady ran unopposed in 2006 and has generally received over 80% of the vote in his campaigns.

District 2

Seven term incumbent Chaka Fattah (D), who was unsuccessful in his bid to be mayor of Philadelphia, ran without major party opposition. Liberal Republican law professor Michael Livingston won the Republican primary, but dropped out of the race due to lack of funding. He was replaced by Adam Lang. This seat is contained in one of the most Democratic districts in the country, with Democrats often winning 90% of the vote. In 2006, Fattah was elected with 88.6% support and in 2008 he won with 88.9% of the vote.

District 3

Seven-term Republican incumbent Phil English faced Democrat Kathy Dahlkemper (campaign website), director of the Erie Arboretum. Steven Porter, the 2006 Democratic nominee, ran as an independent.

English was tested in 2008. He represented a politically balanced Erie-based district that gave George W. Bush 53% of the vote. Also, in 2006, he received just 54% of the vote against an under-funded candidate with no political experience. He has, however, been able to remain a level of popularity due to a moderate voting record and close ties to organized labor.

The DCCC recruited Erie County Councilman Kyle Foust as its top choice to run against English. Dahlkemper, attorney Tom Meyers, and religious nonprofit program coordinator Mike Waltner also declared for the Democratic primary. Dahlkemper proved better at mobilizing support than Foust, the original front-runner, and won the Democratic nomination with 45% of the vote.

District 4

Democratic incumbent Jason Altmire again faced Republican Melissa Hart. In 2006, Altmire defeated incumbent Hart in a 52% to 48% upset. Hart had won 63% of the vote in 2004, when George W. Bush carried this suburban Pittsburgh district with 53%. In 2006, Pennsylvania was perhaps the most disastrous state for incumbent GOP House members, who lost four seats here. Hart ran unopposed for the Republican nomination in 2008 and attempted to use her public service credentials to regain her seat. She previously gained a reputation for appealing to moderate voters despite a conservative track record. She again lost to Altmire, this time by a wider margin than two years prior, with a 56–44% vote.

Altmire maintained close ties with organized labor, possessed experience with the health care issues that are important in a region with an older population, and was supported by the NRA.

District 5

Democrat Mark McCracken, Clearfield County commissioner is running against Republican and Centre County GOP chair Glenn "G.T." Thompson in this open seat election. James Fryman represented the Libertarian Party.

Republican John Peterson announced his intention to retire on January 3, 2007, paving the way for a contentious open seat election. Nine Republicans were in the race for the nomination. Four men emerged as top tier candidates: Thompson, hotel developer Matt Shaner, financial consultant Derek Walker, and former Woodland Township supervisor Jeff Strohmann. Also on the Republican ballot were mortgage broker John Kupa, Clarion mayor John Stroup, Elk County coroner Lou Radkowski, former Centre County commissioner Chris Exarchos, and minister Keith Richardson. Thompson won this hard-fought 9-way primary with just 19% of the vote, in large part due to the late endorsement of Peterson who got involved in the primary campaign 10 days prior to election day. Walker and Shaner proved to be superior fundraisers and aired numerous television and radio commercials to counter Peterson's endorsement of Thompson. The Republican primary included many personal attacks, with Shaner targeting Walker as being political incompetent and Walker referring to a DUI incident involving Shaner. Walker and Thompson were very close in the polls on Election Day, but Thompson received a late boost because of his political track record in Centre County, the district's population center.

McCracken, Lock Haven mayor Richard Vilello, and Bill Cahir, a journalist and Marine Corps veteran of the Iraq War, battled for the Democratic nomination. McCracken won 40% in a hard-fought Democratic race that received much less attention. Despite presenting an open seat opportunity, this race was always viewed as safe for the Republicans, who have generally won over 65% in this district. Prior to 2006, Peterson had previously run in three straight elections without Democratic opposition.

District 6

Three term Republican Jim Gerlach faced Democrat Bob Roggio (campaign website), a retired businessman from Charlestown who ran unopposed for the Democratic nomination both of his opponents dropped out of the race. Gerlach has become used to winning close elections, having survived threats from governor's assistant (and son of the former US Senator) Dan Wofford and attorney Lois Murphy in 2004 and 2006 with approximately 51% each year. The district is a classic swing district that went to John Kerry with 51% in 2004. However, Roggio did not have the name recognition nor the funding that Murphy had when waging her campaign, which made his candidacy more difficult than past challengers.

However, due to the tough environment in 2008 for Republicans, and the fact that Democrats outnumber Republicans this year for the first time in this district, the race was close. In addition, Gerlach has had some trouble shaking a connection to ousted Republican leader Tom Delay, who provided contributions to Gerlach through his PAC. However, Gerlach has a relatively moderate voting record and is seen as a tough campaigner who is knowledgeable in the suburban issues that are important in his district.
