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, the winners of which will serve 6-year terms in the United States Congress from January 3, 2027, to January 3, 2033. Senators are divided into 3 groups, or classes, whose terms are staggered so that a different class is elected every 2 years. Class 2 senators were last elected in 2020, and will be up for election in 2032.

This will be the first Senate election since the 2006 in which the Republican Party won't be led by Mitch McConnell.

Partisan composition
All 33 Class 2 Senate seats are up for election in 2026; Class 2 currently consists of 20 Republicans and 13 Democrats. If vacancies occur in Class 1 or Class 3 Senate seats, that state might require a special election to take place during the, possibly concurrently with the other 2026 Senate elections. This is also the first cycle since 2014 that Arizona will not have a US Senate election.

Change in composition
Each block represents one of the one hundred seats in the U.S. Senate. "D#" is a Democratic senator, "I#" is an Independent senator, and "R#" is a Republican senator. They are arranged so that the parties are separated and a majority is clear by crossing the middle.

Before the elections
Each block indicates an incumbent senator's actions going into the election.

Retirement
As of July 2024, no senators have announced their plans to retire.
