1920 United States House of Representatives elections

The 1920 United States House of Representatives elections were elections for the United States House of Representatives to elect members to serve in the 67th 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 of President Warren G. Harding, the first time that women in all states were allowed to vote in federal elections after the passage of the 19th Amendment.

The incumbent Democratic administration of Woodrow Wilson lost popularity after the conclusion of World War I in 1918, as American voters hoped to return to isolationism and avoid military conflict in the future. Heedless of the prevailing national mood, Wilson advocated American leadership in a new international order under the League of Nations, alienated voters of German and Irish ancestry, and constantly struggled with a Congress controlled by the opposition Republican 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 leader Champ Clark was among those who lost reelection. Clark died 2 days before his term expired.

Although the Southern 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 2026, their greatest number of seats ever.
