Vermont voters will elect all 30 state senators from 16 districts, with each district electing between one and three senators. Districts that elect more than one senator use plurality block voting; in districts that elect two senators, each voter can select up to two candidates on their ballot, and in districts that elect three senators, voters can select up to three candidates. Under Vermont's electoral fusion system, candidates ran receive the nomination of more than one party, with all their nominations being listed on the ballot.
Democrats and Progressives currently hold a 23-seat supermajority in the senate. In order to gain control, Republicans would either need to flip 9 seats in the senate or flip 8 seats and the office of lieutenant governor, which presides over the senate and acts as the tiebreaking vote. However, Republicans would only need to flip 4 seats to break the Democrats' supermajority.
The incumbents are Democrats Brian Campion and Dick Sears, who won with only write-in opposition in 2022. Sears filed to run for re-election, while Campion announced he would retire.[5] However, Sears died in June 2024, shortly after the filing deadline.[6] Sears will remain on the ballot in the August Democratic primary; if he wins, the Vermont Democratic Party will be able to name a replacement nominee.[7]

The incumbent was Democrat Richard Mazza, who won with 73.0% of the vote in 2022. Mazza resigned on April 8, 2024, due to health issues; he later died on May 28.[17] Governor Phil Scott appointed Democrat Andy Julow, a nonprofit executive and former chair of the Champlain Valley School District Board, to Mazza's vacant seat.[18]
