2028 United States Senate elections

The 2028 United States Senate elections will be held on November 7, 2028, with 34 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, 2029, to January 3, 2035. Senators are divided into 3 groups or classes whose terms are staggered so that a different class is elected every 2 years. Class 3 senators were last elected in 2022, and will be up for election again in 2034. These elections will run concurrently with the 2028 United States presidential election.

As of July 2024, one Republican senator, Tim Scott of South Carolina, has already announced plans for retirement; no Republican senators have announced plans to run for re-election; and no Democratic senators either have announced plans for retirement nor are running for re-election.

Partisan composition
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, possibly concurrently with the other 2028 Senate elections.

Change in composition
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.

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

Retirements
As of July 2024, one Republican has announced plans to retire.
