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, which will include the entire term of the president who wins the 2028 presidential election and the first two years of the 2032 presidential election winner's term. Senators are divided into 3 classes whose terms are staggered so that a different class is elected every other year. Class 3 senators were last elected in 2022, and will be up for election again in 2028. These elections will run concurrently with the 2028 United States presidential 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.
