The 1911 United States Senate election in Wisconsin was held in the 50th Wisconsin Legislature on January 25, 1911. Incumbent Republican U.S. senator Robert M. La Follette was re-elected on the first ballot.
In the 1911 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. This was the second U.S. Senate election in Wisconsin carried out after the implementation of partisan primary elections. La Follette won the Republican primary by a wide margin over challenger Samuel A. Cook. U.S. representative Charles H. Weisse won the nomination for Democrats, although the Democratic state convention had voted to support Burt Williams of Ashland.
