2024 United States Senate elections
The 2024 United States Senate elections are scheduled to be held on November 5, 2024, as part of the 2024 United States elections. Thirty-three of the 100 seats in the U.S. Senate will be contested in regular elections. 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 will face election in 2024.

As of April 2024, twenty-four senators (15 Democrats, 9 Republicans, and two independents) are seeking re-election in 2024. Two Senate Republicans (Mike Braun of Indiana and Mitt Romney of Utah), four Senate Democrats (Ben Cardin of Maryland, Tom Carper of Delaware, Debbie Stabenow of Michigan and Joe Manchin of West Virginia), and one Senate Independent (Kyrsten Sinema of Arizona) are not seeking re-election. Democratic Sen. Laphonza Butler of California, who was appointed to her current seat in 2023, is not seeking election in 2024.
Two special Senate elections will take place concurrently with the 2024 regular Senate elections. One of those two special elections will be held in California to fill the vacancy created by the death of longtime Senator Dianne Feinstein for the final two months of her unexpired term, and one will be held in Nebraska following Ben Sasse's 2023 resignation.
Elections analysts consider the map for these Senate elections to be highly unfavorable to Democrats. Democrats will be defending 23 of the 33 Class 1 seats. Three seats being defended by Democrats are in states won by Republican Donald Trump in both 2016 and 2020, while there are no seats in this class held by Republicans in states won by Democrat Joe Biden in 2020. Additionally, Kyrsten Sinema's first term is ending in Arizona, a state that Biden won by less than half a point in 2020; before the end of the 117th Congress, Sinema left the Democratic Party and became an independent. She later announced her retirement in March 2024. In the two previous Senate election cycles that coincided with presidential elections (2016 and 2020), only one senator (Susan Collins in 2020) was elected in a state that was won by the presidential nominee of the opposite party.
