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 again in 2032.

As of January 2024, no Republican senators have announced plans for retirement; no Republican senators have announced plans to run for re-election; no Democratic senators have announced plans for retirement; and five Democratic senators are running for re-election.

This will be the first election cycle since 2014 that no U.S. Senate election will be held in Arizona.

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 119th Congress, possibly concurrently with the other 2026 Senate elections.

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.
