The 1826–27 United States House of Representatives elections were held on various dates in various states between July 3, 1826, and August 30, 1827. Each state set its own date for its elections to the House of Representatives before the first session of the 20th United States Congress convened on December 3, 1827. They occurred during John Quincy Adams's presidency. Elections were held for all 213 seats, representing 24 states.

In these midterm campaigns, the aftershock of the contested 1824 presidential election remained a major issue. The former Democratic-Republican Party had split into two parties, the "Jacksonians," supporting Andrew Jackson (which would later become the Democratic Party) and the "Adams men" or "Anti-Jacksonians," supporters of President John Quincy Adams. Adams's supporters would later come to be known as the National Republican Party. The Jacksonians were able to pick up a slim majority in the House by painting an image of the Adams Men as elitist and of the Jacksonians as the party of the common farmer or artisan. This tactic helped them pick up a number of rural seats.
