2024 United States Senate elections

Summary

The 2024 United States Senate elections were held on November 5, 2024. Regularly scheduled elections were held for 33 out of the 100 seats in the U.S. Senate, and special elections were held in California and Nebraska. U.S. senators are divided into three classes whose six-year terms are staggered so that a different class is elected every two years. Class 1 senators faced election in 2024. Republicans flipped four Democratic-held seats, regaining a Senate majority for the first time in four years, and the most gains for either party since 2014. Republicans successfully defended all of their own seats for the first time since 2014. This was the first time since 1980 that Republicans flipped control of a chamber of Congress in a presidential year.
