The1920 United States House of Representatives elections were elections for theUnited States House of Representatives to elect members to serve in the67th United States Congress. They were held for the most part on November 2, 1920, while Maine held its on September 13. They coincided with the election ofPresidentWarren G. Harding, the first time that women in all states were allowed to vote in federal elections after the passage of the19th Amendment.

The incumbentDemocratic administration ofWoodrow Wilson lost popularity after the conclusion ofWorld War I in 1918, as American voters hoped to return toisolationism and avoid military conflict in the future. Heedless of the prevailing national mood, Wilson advocated American leadership in a new international order under theLeague of Nations, alienated voters of German and Irish ancestry, and constantly struggled with a Congress controlled by the oppositionRepublican Party.

Harding and the Republicans promised a new start for the nation and a disassociation from Europe's political troubles that most voters found appealing. As a result, the Republicans picked up 63 seats in the House of Representatives, with most of the gains coming from Democratic-leaning districts in the big industrial cities and the border states. Many of these districts elected Republican representatives for the only time in decades, and House Democratic leaderChamp Clark was among those who lost reelection. Clark died 2 days before his term expired.

Although theSouthern United States remained solidly Democratic for the most part, the Republicans secured more than 90% of the seats outside the South, which gave them their largest majority of the 20th century and as of 2023, their greatest number of seats ever. The 67th Congress is the most recent in which the Republican Party won greater than a two-thirds majority of seats in either chamber.
