1880–81 United States Senate elections
The 1880–81 United States Senate elections were held on various dates in various states, coinciding with the presidential election of 1880. 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 1880 and 1881, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 1.

The Democratic Party lost five seats. The newly elected Readjuster senator William Mahone caucused with the Republicans, and the Republican Vice President's tie-breaking vote gave the Republicans the slightest majority. This changed when Vice President Chester Arthur ascended to the Presidency on September 19, 1881: with the Vice Presidency vacant during the remainder of Arthur's term, the Senate became evenly divided for the first of three times in history.
