2026 United States Senate elections

The 2026 United States Senate elections are scheduled to be held on November 3, 2026, with 33 of the 100 seats in the Senate being contested in regular elections. In these elections, voters will elect candidates to six-year terms that begin on January 3, 2027, and expire on January 3, 2033. Senators are divided into three classes whose terms are staggered, so that a different class is elected every two years. Class 2 senators were last elected in 2020 and are up for election in 2026. With the election of John Thune as leader of the Republican Conference, this will be the first election year since 2006 in which Senate Republicans are not led by Mitch McConnell. The Senate Democratic Conference has been led by Chuck Schumer since 2017. Special elections have been scheduled in Ohio and Florida, following the resignation of JD Vance to become Vice President and Marco Rubio's resignation to become United States Secretary of State. This is the most recent election cycle in which an elected incumbent senator—Bill Cassidy of Louisiana—both lost renomination and placed no better than third in a primary. The last incumbent senator to lose renomination was Richard Lugar in 2012. The last incumbent senator to place no better than third in a primary was Hattie Caraway in 1944.
