2028 United States Senate elections

All 34 Class 3 Senate seats are up for election in 2028; Class 3 currently consists of 19 Republicans and 15 Democrats. If vacancies occur in Class 1 or Class 2 Senate seats, that state might require a special election to take place during the 120th Congress, possibly concurrently with the other 2028 Senate elections.

Each block represents one of the one hundred seats in the U.S. Senate. "D#" is a Democratic 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.
