The 1924 United States Senate elections were elections for the United States Senate which coincided with the election of Republican President Calvin Coolidge to a full term. The 32 seats of Class 2 were contested in regular elections, and special elections were held to fill vacancies. The strong economy and Coolidge's popularity helped Republican candidates increase their majority by three. Republicans would gain another seat through mid-term vacancies, bringing their seat share to 56âÂÂ39âÂÂ1.
Three Republicans and two Democrats retired instead of seeking re-election.
Four Democrats, four Republicans, and one Farmer-Labor candidate sought re-election but lost in the primary or general election.

In these special elections, the winners were seated during 1924 or before March 4, 1925; ordered by election date.
In these general elections, the winners were elected for the term beginning March 4, 1925; ordered by state.
All of the elections involved the Class 2 seats.

The tipping point state was Wyoming, with a margin of 10.4%.
Democrat Daniel F. Steck successfully challenged the election, and the Senate awarded Steck the seat on April 12, 1926.
Incumbent Democrat Thomas J. Walsh, who was first elected to the Senate in 1912 by the state legislature (as was the practice then), and re-elected in 1918 by popular vote (in accordance with the 17th Amendment), ran for re-election. He was unopposed in the Democratic primary.
He faced former State Representative Frank Bird Linderman and several other opponents in the general election. Walsh ultimately won re-election to his third term by a solid margin.
