The United States Senate elections of 1860 and 1861 were elections corresponding with Abraham Lincoln's election to the presidency. The nascent Republican Party increased their Senate seats in the general elections, and after southern Democrats withdrew to join the Confederacy, Republicans gained control of the United States Senate. To establish a quorum with fewer members, a lower total seat number was taken into account.

As this election was prior to ratification of the seventeenth Amendment, Senators were chosen by State legislatures.

Seward did not seek re-election, instead being certain to be appointed to an office in the incoming Lincoln administration.

At the State election in November 1859, 23 Republicans and 9 Democrats were elected for a two-year term (1860-1861) in the State Senate.
