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, the winners of which will serve six-year terms in the United States Congress from January 3, 2027, to January 3, 2033. Senators are divided into three groups, or classes, whose terms are staggered, so that a different class is elected every two years. Class 2 senators were last elected in 2020, and will be up for election in this cycle.
Two special elections will be held: one in Ohio, to fill the remaining two years of JD Vance's term following his election to the vice presidency; and one in Florida, to fill the remaining two years of Marco Rubio's term, after his nomination as the United States Secretary of State was confirmed. With the election of John Thune as leader of the Republican Conference, this will be the first election year since 2006 in which the Republicans are not led by Mitch McConnell, who is retiring at the end of his term.
