2026 United States Senate elections (YoungLibertarian20)

The 2026 United States Senate elections will be held on November 3, 2026, with 34 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. A special election was held in the state of South Carolina to elect a Senator to fill the seat previously held by Tim Scott, who had been elected Vice President of the United States in 2024. 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 again in 2026.

Three Democrats and five Republicans announced their retirements from the U.S. Senate in this cycle. The Republicans, holding a significant advantage before the election, easily retained the Senate despite three Democratic pickups. Incumbent Senators Susan Collins, John Cornyn and Thom Tillis lost re-election to their Democratic challenger. John Cornyn's loss was the most high-profile loss in being the Senate Majority Whip at the time. In total, there was three Democratic pickups. The remaining eight open seats were won by the party it was previously held by.
