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 six-year terms in the United States Congress from January 3, 2027, to January 3, 2033. Senators are divided into three groups, or classes, whose terms are staggered so that a different class is elected every two years. Class 2 senators were last elected in 2020 and will be up for election in this cycle.

A special election in Ohio will be held to fill the remaining two years of JD Vance's term following his election to the vice presidency. In Florida, one may also be held to fill the remaining two years of Marco Rubio's term should his nomination as the United States Secretary of State be confirmed. With the election of John Thune as leader of the Republican Conference, this will be the first election year since 2006 in which the Republicans will not be led by Mitch McConnell.

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 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. Michigan elected Democrat Elissa Slotkin to the Senate in 2024 by 0.3 points; Georgia did not have a Senate election in 2024.^[1]

There are five incumbent Democratic senators that represent states won by Kamala Harris by single-digit margins in 2024: New Hampshire's Jeanne Shaheen, Minnesota's Tina Smith, Virginia's Mark Warner, New Jersey's Cory Booker, and New Mexico's Ben Ray Luján.

There is one seat with a Republican incumbent in a state won by Kamala Harris in 2024: Maine, where Senator Susan Collins was re-elected to a fifth term in 2020; Angus King, an independent, was re-elected by 17 points. One Republican, Senator Thom Tillis of North Carolina, is up for re-election in a state won by Trump by a single-digit margin.

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.
