Elections to the United States House of Representatives were held in Pennsylvania on October 13, 1812, for the 13th Congress.
In the previous election, 17 Democratic-Republicans and 1 Federalist had been elected to represent Pennsylvania.
Pennsylvania was divided at this time into 15 districts, 9 of which were single-member districts, five of which had two members, and one of which had four members. Following the 1810 census, Pennsylvania underwent redistricting. Most of the new districts had little correspondence to the former districts, for example, the old 3rd district was divided between the new 2nd, 3rd, and 7th districts. The 1st, 9th and 10th districts were unaltered, except for renumbering of the old 9th and 10th to 13th and 12th respectively, and the addition of a 4th seat to the 1st district.
Sixteen incumbents (all Democratic-Republicans) ran for re-election, of whom 14 were re-elected. The incumbents James Milnor (F) of the and Joseph Lefever (DR) of the old did not run for re-election. The two incumbents who lost re-election lost to members of the same party, while six of the seven open seats were won by Democratic-Republicans, a net increase of 5 seats for the Democratic-Republicans and no change for the Federalists.
