The 2026 United States Senate elections are scheduled to be held on November 3, 2026, with 33 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, 2027, to January 3, 2033, plus a special election in Ohio will be held to fill the remaining 2 years of JD Vance's term following his election to the vice presidency. Senators are divided into 3 groups, or classes, whose terms are staggered so that a different class is elected every 2 years. Class 2 senators were last elected in 2020, and will be up for election in 2026. This will be the first since 2006 where Mitch McConnell will not be the Republican Senate leader.

All 33 Class 2 Senate seats and two Class 3 seats are up for election in 2026; Class 2 currently consists of 20 Republicans and 13 Democrats. If vacancies occur in Class 1 or other 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.

There are two seats being defended by Democrats in states won by Donald Trump in 2024 (in both cases, by less than three percentage points): Michigan, where the incumbent is Gary Peters, and Georgia, where the incumbent is Jon Ossoff. There is one seat in a state won by Democrats (by six percentage points) that were being defended by Republicans: Maine, where the incumbent is Susan Collins. Six Democrats represent states won by Kamala Harris by single-digit margins in 2024, while only one other Republican represents a state won by Trump by a single-digit margin in 2024.

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.

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