The 1848–49 United States House of Representatives elections were held on various dates in various states between August 1848 and November 1849. Each state set its own date for its elections to the House of Representatives before the first session of the 31st United States Congress convened on December 3, 1849. The new state of Wisconsin elected its first representatives, and California also held its first congressional elections before officially achieving statehood in 1850, increasing the size of the House to 233 seats.

These elections spanned the 1848 United States presidential election and took place amid the U.S. victory over Mexico in the (1846–48) Mexican–American War. The Whigs lost their House majority as Democrats, whose support had driven the war, gained a House plurality. Among minor parties, the Free Soil Party won nine Northern seats, while the American or "Know Nothing" Party retained one.

Following the discovery of gold in January 1848, California boomed, creating immediate pressure for statehood. The Compromise of 1850, though largely crafted in the Senate, was also passed by the House, brokering its admission to the Union. Anticipating statehood, California elected two members at-large on November 13, 1849, to be seated September 11, 1850.

As neither major party held a majority when Congress convened on December 3, 1849 ⁠— the Democrats finished three seats short, while the Whigs had lost 12 seats and the majority ⁠— the election of a Speaker proved contentious.

The Whigs were sectionally split, with Northern Whigs nominating incumbent speaker Robert C. Winthrop of Massachusetts and Southern Whigs supporting of Tennessee. Democrats primarily supported Howell Cobb of Georgia; 13 other Democratic hopefuls also garnered support. The small Free Soil Party, opposing expansion of slavery into the Western territories, supported David Wilmot of Pennsylvania, author of the Wilmot Proviso, calling attention to slave power's hold over both major parties.

After nearly three weeks of heated debate, the House suspended its majority rule for the Speaker election: Cobb was elected on the 63rd ballot by plurality.^[1]

Wisconsin was apportioned an additional seat in 1848,^[2] and two more seats were added for the new state of California.^[3]
