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

Thirteen Representatives (8 Democratic-Republicans and 7 Federalists) had been elected in the previous election Pennsylvania was divided into 12 districts, one of which (the 4th) was a plural district, with 2 Representatives.

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 Nine incumbents (8 Democratic-Republicans and 1 Federalist) ran for re-election, all of whom won re-election.

In the 4th district, Peter Muhlenberg (DR) was elected to the Senate on November 27, 1800, while in the 12th 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
