The 1881 United States Senate special election in Wisconsin was held in the 34th Wisconsin Legislature between March 9, 1881, and March 10, 1881. The special election was necessary to complete the unexpired term of U.S. Senator Matthew H. Carpenter, who died February 24, 1881. Former U.S. Senator Angus Cameron, who did not seek re-election in 1881 and left office just days before the special election, was elected to succeed Carpenter.

In the 1881 term, Republicans held overwhelming majorities in both chambers of the Wisconsin Legislature, so had more than enough votes to elect a Republican United States senator. The main contest was in the Republican legislative caucus, where former U.S. senator Angus Cameron outlasted Wisconsin Republican Party boss Elisha W. Keyes, taking the nomination on the 48th ballot.
