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 120th Congress, 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.

One-term Democrat John Fetterman was elected in 2022 with 51.2% of the vote. He has filed paperwork to run for re-election.
Former Democratic Representative Conor Lamb has been seen as a potential primary challenger given his criticism of Fetterman amid liberal discontent with the senator for not opposing President Trump and the Republican party enough, not holding town halls and public events since the November 2024 elections, voting to confirm some of Trump's nominees, and advocating for the United States to bomb Iran while continuously and repeatedly criticizing Democrats such as condemning the party's rhetoric towards Trump. He has been a longtime rival of Fetterman and was one of his two primary opponents in 2022. Other potential Democratic primary challengers include state representative Malcolm Kenyatta, state senator Maria Collett, and U.S. Representatives Brendan Boyle, Madeleine Dean, Chris Deluzio, and Chrissy Houlahan.
