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. These elections ran concurrently with the 2024 United States presidential election in which Kamala Harris lost to Donald Trump.

A total of 25 U.S. senators (14 Democrats, nine Republicans, and two independents) sought re-election in 2024, while seven senators declined to seek re-election. In addition, Democrats Sen. Laphonza Butler of California and Sen. George Helmy of New Jersey – 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 of Dianne Feinstein's term following her death in September 2023; and one in Nebraska, to fill the remaining two years of Ben Sasse's term following his resignation in January 2023.

Republicans won control of the U.S. Senate by flipping an open independent-held seat in West Virginia; defeating Democratic incumbents in Montana, Ohio, and Pennsylvania; 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 in Arizona, Michigan, Nevada, and Wisconsin, despite Trump having won those states. No Republican won in a state that Kamala Harris carried in the presidential election. This election cycle saw all but five Senate seats shift towards the Republicans from 2018, representing a record number of seats that shifted in the same direction as the party that concurrently won the White House.

Partisan composition

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

Burgess Everett of Politico considered the map for these Senate elections to be highly unfavorable to Democrats. Democrats were to defend 23 of the 33 Class 1 seats, including three in states won by Republican Donald Trump in both 2016 and 2020. In contrast, there are no seats in this class held by Republicans in states won by Democrat Joe 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.

Republican gains were attributed to better candidate quality compared to 2022 and to the coattails of Republican presidential candidate Donald Trump, who won the 2024 presidential election. 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". 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 of Non-Hispanic White voters increasing from 67% to 71% of the electorate and the Republicans winning 46% of Latinos, as well as mentioning polling's "continued underestimation of Republicans' support nationally and in the key swing states".

Split-ticket voting

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. 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.

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. 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.

Predictions

Several sites and individuals published predictions of competitive seats. These predictions looked at factors such as the strength of the incumbent (if the incumbent was running for reelection) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook 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

One-term independent Kyrsten Sinema was narrowly elected in 2018 as a Democrat with 50.0% of the vote. She left the Democratic Party in December 2022. Sinema announced on March 5, 2024, that she would not run for reelection. Prior to her retirement announcement, Sinema was considered vulnerable to challengers from the Democratic Party due to her opposition to some of President Joe Biden's agenda, and U.S. representative Ruben Gallego launched an early bid for the Democratic nomination, which he won with no opposition. Pinal County sheriff Mark Lamb and 2022 gubernatorial nominee Kari Lake sought the Republican nomination for U.S. Senate. Lake won the Republican primary by less than expected.

Five-term Democrat Dianne Feinstein was reelected in 2018 with 54.2% of the vote against another Democrat. On February 14, 2023, Feinstein announced that she would not seek reelection to a sixth term. However, she died on September 29, 2023, leaving the seat vacant. Democrat Laphonza Butler, president of EMILY's List, was appointed by California governor Gavin Newsom to succeed Feinstein on October 2, 2023. Butler did not run for election to a full term, or for the final two months of the current term.

There were three major Democratic candidates for the seat — U.S. representatives Barbara Lee, Katie Porter, and Adam Schiff — along with former professional baseball player Steve Garvey running as a Republican. Schiff was viewed as representing the establishment wing of the Democratic Party, while Porter and Lee represent the progressive wing.

Schiff and Garvey won the nonpartisan primary election which took place on March 5, 2024, during Super Tuesday, setting up a general election campaign between the two. Schiff narrowly secured the first place in the regular primary with just 0.05% of the vote over Garvey, but fell short of it in the special one by 4%. However, the three leading Democrats overall performed better in the special primary, with 58.2% of the vote compared to 56.7%. Due to California's election rules, similar to the previous election for the other seat, there were two ballot items for the same seat: a general election, to elect a Class 1 senator to a full term beginning with the 119th United States Congress, to be sworn in on January 3, 2025; and a special election, to fill that seat for the final weeks of the 118th Congress.

Schiff was considered a heavy favorite, and easily won both the regular and special general elections with more than 58% of the vote. Schiff became the first male U.S. senator from this seat since John Seymour left office in 1992 and California one of several states to have a younger senior senator (Alex Padilla) and an older junior senator (Schiff). With over 41% of the vote in the general election, Garvey had the best performance of any Republican candidate for this seat since 1994. Garvey managed to win Orange County, which voted for Kamala Harris in the concurrent presidential election. He also flipped three counties compared to the 2022 Senate election: Lake, Imperial, and San Joaquin counties. With over 6.3 million votes in the regular election, Garvey set the record for the most votes ever received by a Republican candidate in a single state for any election, as Donald Trump was the runner up with 200,000 fewer votes in the concurrent presidential election.

Former governor and incumbent one-term Republican Rick Scott was narrowly elected in 2018 with 50.06% of the vote. He ran for reelection to a second term. Brevard County assistant district attorney Keith Gross and actor John Columbus challenged Scott for the Republican nomination.

Scott won a second term, defeating Democratic former congresswoman Debbie Mucarsel-Powell. With the benefit of incumbency and the state's rightward trend, most political pundits considered the race to be favoring Scott to win re-election. On Election Day, Scott won by 12.78 percentage points, a significantly larger margin than most pre-election polls had suggested.

Three-term Democrat Ben Cardin was reelected in 2018 with 64.9% of the vote. On May 1, 2023, Cardin announced he was not running for reelection.

Prince George's County executive Angela Alsobrooks defeated U.S. representative David Trone for the Democratic nomination after a contentious primary, where Trone spent heavily from his personal wealth while Alsobrooks had the support of most elected Democrats. Former governor Larry Hogan easily defeated conservative former state delegate Robin Ficker for the Republican nomination. A popular moderate known for his political independence, Hogan had previously declined to run, but unexpectedly filed to run hours before the candidate filing deadline.

Angela defeated Horgan by a 11 point margin, a significant drop from Cardin's 2018 performance. Hogan's margin was 17 points better than Trump's margin in Maryland, the largest gap between senatorial and presidential margins in the 2024 cycle, and this election was the closest Senate race in Maryland since 2006. Hogan carried Anne Arundel and Frederick counties—both won by Kamala Harris in the presidential race—and became the first Republican to exceed one million votes in a Maryland U.S. Senate election, the highest total for a Republican in the state's history. Despite this, Hogan could not overcome Alsobrooks's margins in the Washington–Baltimore metropolitan area, and lost the election by nearly 12 points.

Four-term Democrat Debbie Stabenow was reelected in 2018 with 52.3% of the vote. She announced on January 5, 2023, that she would retire, and would not run for a fifth term.

Representative Elissa Slotkin and actor Hill Harper ran for the Democratic nomination. Former U.S. representatives Mike Rogers and Justin Amash, and hedge fund manager Sandy Pensler ran for the Republican nomination. The nominees were Slotkin and Rogers, who easily won their primaries as expected.

Stolki narrowly defeated Rogers in general election by a 0.34% margin. Stolki won 48.64% of the vote compared to Rogers' 48.3%. On November 6, 2024, major news organizations projected that Slotkin had won the election. Slotkin received 23,847 fewer votes than Kamala Harris, while Rogers received 122,956 fewer votes than Donald Trump. As Republican presidential nominee Donald Trump carried Michigan on the same ballot, this was the first time Michigan voted for candidates of different political parties for U.S. senator and president since Democrat Don Riegle was re-elected as Republican George H. W. Bush carried the state in 1988.

One-term Democrat Jacky Rosen was elected in 2018 with 50.4% of the vote. Rosen was re-elected for a second term. Veteran and 2022 Senate candidate Sam Brown was declared the Republican nominee after winning the June 11 primary. Brown easily won against former ambassador to Iceland Jeffrey Ross Gunter and former state assemblyman Jim Marchant, among others.

Rosen was reelected by a very slim margin of around 1.7%, an advantage of around 24,000 votes among over 1.46 million cast statewide. This result reflected a somewhat more competitive result than expected, according to final polling averages, and was down from her 2018 margin of around 5 points against then-incumbent Republican senator Dean Heller. Rosen received 47.9% of the statewide vote to Brown's 46.2%.

Initially, despite the Associated Press calling the race for McCormick, Casey refused to concede the race due to unknown numbers of outstanding provisional ballots in primarily urban areas. Senate majority leader Chuck Schumer originally did not invite McCormick to the “New Senator Orientation Event,” but Schumer relented after criticism from Republicans and independent Arizona senator Kyrsten Sinema. Casey eventually conceded on November 21; McCormick was then officially declared the winner.
