The 1812 United States general election elected the members of the 13th United States Congress. The election took place during the First Party System, and shortly after the start of the War of 1812. The Federalist Party made a relatively strong showing, winning seats in both chambers while supporting a competitive challenge to the incumbent Democratic-Republican President. However, the Democratic-Republican Party continued its control of the Presidency and both houses of Congress.
In the Presidential election, incumbent Democratic-Republican President James Madison defeated Lieutenant Governor and Mayor DeWitt Clinton. Clinton was a member of the Democratic-Republican Party, but his presidential bid received the support of both anti-Madison Democratic-Republicans and many Federalists. Although Madison won, the Presidential election was the closest since the 1812 election.
Following the 1810 census, 39 seats were added to the House. Federalists won major gains, but Democratic-Republicans continued to dominate the chamber.
In the Senate, Federalists picked up a small number of seats, but Democrats retained a dominant majority.
