The United States Senate elections of 1920 and 1921 were elections for the United States Senate which coincided with the election of Warren G. Harding as President. Democrat Woodrow Wilson's unpopularity allowed Republicans to win races across the country, winning ten seats from the Democrats, providing them with an overwhelming 59 to 37 majority. The Republican landslide was so vast that the Democrats failed to win a single race outside the South.

Republicans won two seats that were open from retiring Democrats, one seat from a Democrat who had lost renomination, and they defeated seven Democratic incumbents.
