The '''1850–51 United States House of Representatives elections''' were held on various dates in various states between August 5, 1850, and November 4, 1851. Each state set its own date for its elections to the [[United States House of Representatives|House of Representatives]] before the first session of the [[32nd United States Congress]] convened on December 1, 1851. Elections were held for all 233 seats, representing 31 states.

The [[Democratic Party (United States)|Democrats]] gained 17 seats, increasing their majority relative to the rival [[Whig Party (United States)|Whigs]], who lost 22 seats. Incumbent Whig [[President of the United States|President]] [[Millard Fillmore]], who succeeded to the Presidency in July 1850 after the death of more charismatic General [[Zachary Taylor]], lacked a strong political base. The [[Compromise of 1850]], which admitted [[California]] alone as a free state in exchange for concessions to slave state interests, began integration of the [[Mexican Cession]]. It appeared in the short term that Congress had politically feasible options to contain [[sectionalism]] and to reduce tensions over expanding [[Slavery in the United States|slavery]] in the West. This optimism soon would prove unfounded.

The [[Union Party (United States, 1850)|Union Party]], formed in support of the [[Compromise of 1850]], gained 10 seats in the South, as did the [[Southern Rights Party]]. The [[Free Soil Party]], which opposed the expansion of slavery into the Western territories, lost five seats and was reduced to four Representatives, all in [[New England]].
