The 1868–69 United States Senate elections were held on various dates in various states. 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 1868 and 1869, 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 Republican Party maintained their Senate majority. Six former Confederate states were then readmitted separately from the regular election, each electing two Republicans. This increased the Republicans' already overwhelming majority to the largest proportion of seats ever controlled by the party.
