The2024 United States Senate elections were held on November 5, 2024. Regularly scheduled elections were held for 33 out of the 100 seats in theU.S. Senate,^[4][5] and special elections were held inCalifornia^[6] andNebraska.^[7] U.S. senators are divided into threeclasses whose six-year terms are staggered so that a different class is elected every two years.^[8] Class 1 senators faced election in 2024.^[9] Republicans flipped four Democratic-held seats, regaining a Senate majority for the first time in four years, and the most gains for either party since2014. 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.^[10]

A total of 26 U.S. senators (15Democrats, nineRepublicans, and twoindependents) sought re-election in 2024,^[11] while seven senators declined to seek re-election.^[12] In addition, Sen.Laphonza Butler of California^[13] and Sen.George Helmy of New Jersey^[14] – each of whom had been appointed to their respective Senate seats – did not seek election in 2024. Concurrent with the 2024 regular Senate elections, two special Senate elections took place: one in California, to fill the final two months ofDianne Feinstein's term following her death in September 2023; and one in Nebraska, to fill the remaining two years ofBen Sasse's term following his resignation in January 2023.^[15][16][17]

Republicans won control of the U.S. Senate by flipping an open independent-held seat inWest Virginia; defeating Democratic incumbents inMontana,Ohio, andPennsylvania; and retaining all the seats they had previously held. Democrats flipped a seat in Arizona from an Independent who caucused with the Democrats. Democratic candidates were elected inArizona,Michigan,Nevada, andWisconsin, despite Trump having won those states. No Republican won in a state thatKamala Harris carried in the presidential election.

All 33Class 1 Senate seats, and one Class 2 seat, were up for election in 2024; Class 1 currently consisted of 20 Democrats, four independents whocaucus with the Senate Democrats,^[e] and 10 Republicans.

Burgess Everett ofPolitico considered the map for these Senate elections to be highly unfavorable to Democrats. Democrats were to defend 23 of the 33 Class 1 seats,^[20] including three in states won by RepublicanDonald Trump in both2016 and2020. In contrast, there are no seats in this class held by Republicans in states won by DemocratJoe Biden in 2020. In the previous Senate election cycle that coincided with a presidential election (2020), only one senator (Susan Collins of Maine) was elected in a state that was simultaneously won by the presidential nominee of the opposite party.^[21]

Republican gains were attributed to better candidate quality compared to2022^[22] and to thecoattails of Republican presidential candidateDonald Trump, who won the2024 presidential election.^[23]Time's Eric Cortellessa wrote that the thesis of the Republicans' success boiled down to the simple slogan "Max out the men and hold the women", meaning emphasizing the economy and immigration, which Trump did "relentlessly". Cortellessa also mentioned Trump's minimization of his numerous controversies, and push-offs of criminal trials via "a combination of friendly judges and legal postponements" to after the election. He said Trump's "advanced age and increasingly incoherent trail rhetoric" were taken by voters in stride, and that "much of the country read Trump's legal woes as part of a larger corrupt conspiracy to deny him, and them, power".^[24]NPR wrote that "Americans have continued to chafe at higher than pre-pandemic prices and the lack of affordable housing", and that much of the voter placed the blame "squarely" on the Biden administration, wishing for the economy that had existed under the prior Trump Administration. NPR noted that demographics played an important role, with the share ofNon-Hispanic White voters increasing from 67% to 71% of the electorate and the Republicans winning 46% ofLatinos, as well as mentioning polling's "continued underestimation of Republicans' support nationally and in the key swing states".^[25]

The 2024 Senate elections saw a notable increase in split-ticket outcomes compared to recent cycles. Four states that Donald Trump won in the presidential election also elected Democratic senators: Arizona, Michigan, Nevada, and Wisconsin.^[26] This represented approximately 12 percent of states with both contests on the ballot producing split outcomes—the highest share since 2012, when 18 percent of states split their tickets between presidential and Senate races.^[27]

Despite the split outcomes, the correlation between presidential and Senate race margins remained historically high at approximately 0.95, indicating that while some states elected different parties to each office, the margins in both races tracked closely together.^[28] The results also contributed to a historically low number of split Senate delegations, with only three states—Maine, Pennsylvania, and Wisconsin—having senators from different parties in the incoming 119th Congress, the lowest number since direct popular election of senators began in 1914.^[29]

Each block represents one of the 100 seats in the U.S. Senate. "D#" is a Democratic/active senator, "I#" is an Independent senator, and "R#" is a Republican/active senator. They are arranged so that the parties are separated, and a majority is clear by crossing the middle.

Each block indicates an incumbent senator's actions going into the election.

Several sites and individuals published predictions of competitive seats. These predictions looked at factors such as the strength of theincumbent (if the incumbent was running for reelection) and the other candidates, and the state's partisan lean (reflected in part by the state'sCook Partisan Voting Index rating). The predictions assigned ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors used:

• "tossup": no advantage
• "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
• "lean" or "leans": slight advantage
• "likely": significant, but surmountable, advantage
• "safe" or "solid": near-certain chance of victory

Two Independents, two Republicans and five Democrats retired instead of seeking re-election. SenatorDianne Feinstein had previously announced her intent to retire at the end of her term; however, she died in office on September 29, 2023.

Three Democrats sought re-election but lost in the general election.

In each special election, the winner's term begins immediately after their election is certified by their state's government.

Elections are sorted by date, then state.

In these general elections, the winners were elected for the term beginning January 3, 2025.

11 races had a margin of victory under 10%:^[49]
