The 1840–41 United States House of Representatives elections were held on various dates in various states between July 6, 1840 and November 2, 1841. Each state set its own date for its elections to the House of Representatives, before or after the first session of the 27th United States Congress convened on May 31, 1841. Elections were held for all 242 seats, representing 26 states.

In a Whig wave, voters gave the Whig Party a House majority for the first time. Most Americans experienced the Panic of 1837 as a severe economic downturn. Its perceived mishandling by Democratic President Martin Van Buren fueled new support for alternative economic policies favored by Whigs of which voters had previously been skeptical. Collapse of the Anti-Masonic Party in the late 1830s also drove some third-party incumbents into the Whig Party. Newly elected members included Robert M. T. Hunter, Independent of Virginia, and Zadok Casey, Independent Democrat of Illinois.
