1820 and 1821 United States Senate elections

The 1820 and 1821 United States Senate elections were elections for the United States Senate that, corresponding with James Monroe's landslide re-election, had the Democratic-Republican Party gain one-to-five seats (in the general and special elections), assuming almost complete control of the Senate.

As these elections were prior to ratification of the seventeenth amendment, senators were chosen by state legislatures.
