The 2024 United States Senate election in Michigan was held on November 5, 2024, to elect a Class I member of the United States Senate to represent the state of Michigan. It was held concurrently with the 2024 United States presidential election, other elections to the U.S. Senate, elections to the U.S. House of Representatives, and various state and local elections. Democratic congresswoman Elissa Slotkin won her first term in office, narrowly defeating Republican former congressman Mike Rogers. She succeeded Democratic incumbent Debbie Stabenow, who did not seek a fifth term.

Primary elections took place on August 6, 2024. Slotkin won the Democratic nomination with 76% of the vote over actor Hill Harper, and Rogers won the Republican nomination with 63% of the vote over former congressman Justin Amash. 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.

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.

Background Michigan is considered to be a purple state. However, Democrats had seen much more success in recent years in the state. At the time of the election, Democrats controlled both U.S. Senate seats, seven of 13 of the U.S. House congressional delegation, the minimum majority in both houses of the Michigan Legislature, and all statewide offices.

This race was considered to be competitive given the state's nearly even partisan lean and that there was no incumbent; however, most polls and ratings had Slotkin as the slight favorite to win. In-fighting among Michigan Republicans after the 2022 elections left the state party poor in funding for the U.S. Senate race and defaulting on a bank loan. The MIGOP also failed to meet campaign finance reporting deadlines.

Democratic primary Campaign Elissa Slotkin led the field in fundraising with nearly $16 million raised as of April 2024. Nearly $6 million of this had been raised before August 2023. She continued to dominate fundraising in the second quarter of 2024 outpacing her Republican opponent by as much as three-to-one with 95% of her contributions coming from donors giving $100 or less according to the campaign.

Slotkin released the first TV ad of the primary campaign on May 28 which focused on her work in national security in the George W. Bush and Obama administrations.

Campaign contribution allegations In November 2023, Hill Harper claimed that he had been offered $20 million in campaign contributions from former Motown Motion Picture Studios owner Linden Nelson if he would drop out of the Senate race to mount a primary challenge against U.S. Representative Rashida Tlaib. The allegation was denied by Nelson. Nasser Beydoun subsequently also alleged that former Michigan Democratic Party chair Lon Johnson had approached him with an identical offer to drop out of the Senate race and primary Tlaib. Johnson denied the claims, saying, "that's just crazy. I didn't offer him $20 million, or any other amount of money, to run against Rashida. That's insane." Beydoun was later disqualified from the ballot.

Campaign Amash, Pensler and Rogers were certified to be on the Republican primary ballot at the end of May.

Residency controversy Even though Rogers is a former Michigan congressman, he owns a home in Cape Coral, Florida, and was registered to vote in Florida in 2022. He subsequently purchased a home in White Lake Township, living outside Brighton while that home is remodeled. He also changed his voting registration back to Michigan. His Florida residency became the subject of negative ads against him. New controversy arose regarding the completion of Rogers's new home.
