2026 United States Senate elections

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.

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.
