1800 United States House of Representatives elections in Pennsylvania

Elections to the United States House of Representatives were held in Pennsylvania on October 14, 1800, for the 7th Congress.

Background
Thirteen Representatives (8 Democratic-Republicans and 7 Federalists) had been elected in the previous election

Congressional districts
Pennsylvania was divided into 12 districts, one of which (the PA's 4th congressional district) was a plural district, with 2 Representatives. This was the last election which used these districts.
 * The PA's 1st congressional district consisted of the City of Philadelphia
 * The PA's 2nd congressional district consisted of Philadelphia County
 * The PA's 3rd congressional district consisted of Chester and Delaware Counties
 * The PA's 4th congressional district (2 seats) consisted of Montgomery, Bucks and Northampton Counties
 * The PA's 5th congressional district consisted of Berks and Luzerne County
 * The PA's 6th congressional district consisted of Northumberland and Dauphin Counties
 * The PA's 7th congressional district consisted of Lancaster County
 * The PA's 8th congressional district consisted of York County
 * The PA's 9th congressional district consisted of Mifflin and Cumberland County
 * The PA's 10th congressional district consisted of Bedford, Huntingdon and Franklin Counties
 * The PA's 11th congressional district consisted of Westmoreland and Fayette Counties
 * The PA's 12th congressional district consisted of Allegheny and Washington Counties

The counties that made up the 5th district did not border each other. That district was therefore made up of two separate pieces rather than being a single contiguous entity

Note: Many of these counties covered much larger areas than they do today, having since been divided into smaller counties

Election results
Nine incumbents (8 Democratic-Republicans and 1 Federalist) ran for re-election, all of whom won re-election. The incumbents Robert Waln (F) of the PA's 1st congressional district, Richard Thomas (F) of the PA's 3rd congressional district, John W. Kittera (F) of the PA's 7th congressional district and Thomas Hartley (F) of the PA's 8th congressional district did not run for re-election. Ten Democratic-Republicans and three Federalists were elected, a net gain of 2 seats for the Democratic-Republicans.

Special elections
There were three special elections following the October elections, one of which was for the outgoing Congress.

In the PA's 4th congressional district, Peter Muhlenberg (DR) was elected to the Senate on November 27, 1800, while in the PA's 12th congressional district, Albert Gallatin (DR) was appointed Secretary of the Treasury in May, 1801. Neither served in the 7th Congress, and special elections were held in both districts on October 13, 1801
