The 1828–29 United States House of Representatives elections were held on various dates in various states between July 9, 1828 and October 5, 1829. Each state set its own date for its elections to the House of Representatives before the first session of the 21st United States Congress convened on December 7, 1829. Elections were held for all 213 seats, representing 24 states. They occurred while Jacksonians soundly took control of the presidency, with Andrew Jackson's victory, they greatly increased their majority in Congress. Outgoing President John Quincy Adams's unpopularity played a major role in the Jacksonian pick-up, as did the perception of the Anti-Jacksonian Party as urban and elitist. Major increases in suffrage also heightened Jacksonian wins, as newly enfranchised voters tended to associate with Jacksonian principles. The Anti-Masonic Party, a single issue faction based on distrust of Freemasonry, became the first third party in American history to garner seats in the House.
