The 2030 United States Senate elections will be held on November 5, 2030, with 33 of the 100 seats in the Senate being contested in regular elections, the winners of which will serve 6-year terms in the United States Congress from January 3, 2031, to January 3, 2037, which will include the last 2 years of the 2028 presidential election winner's term, and the entirety of the 2032 presidential election winner's term. Senators are divided into 3 groups or classes whose terms are staggered so that a different class is elected every 2 years. Class 1 senators were last elected in 2024 and will be up for election again in 2030.
All 33 Class 1 Senate seats are up for election in 2030; Class 1 currently consists of 14 Republicans, 17 Democrats, and two independents. If vacancies occur in Class 2 or Class 3 Senate seats, that state might require a special election to take place during the , possibly concurrently with the other 2030 Senate elections.
