The 1820–21 United States Senate elections were held on various dates in various states, corresponding with James Monroe's landslide re-election. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1820 and 1821, and a seat may have been filled months late or remained vacant due to legislative deadlock.^[1] In these elections, terms were up for the senators in Class 1.

The Democratic-Republican Party gain one-to-five seats (in the general and special elections), assuming almost complete control of the Senate.
