United States House of Representatives elections in Pennsylvania, 1800
Elections to the United States House of Representatives in Pennsylvania for the 7th Congress were held October 14, 1800.
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 4th) was a plural district, with 2 Representatives. This was the last election which used these districts.
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 who won re-election. The incumbents Robert Waln (F) of the 1st district, Richard Thomas (F) of the 3rd district, John W. Kittera (F) of the 7th district and Thomas Hartley (F) of the 8th 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.
