2024 United States Senate elections


The 2024 United States Senate elections will be held on November 5, 2024, 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, 2025, to January 3, 2031. Senators are divided into three groups, or classes, whose terms are staggered so that a different class is elected every two years. Class 1 senators were last elected in 2018, and will be up for election again in 2024.

Partisan composition

All 33 Class 1 Senate seats are up for election in 2024; Class 1 currently consists of 21 Democrats, 2 independents who caucus with the Senate Democrats and 10 Republicans.

Change in composition

Each block represents one of the one hundred seats in the U.S. Senate. "D#" is a Democratic/active senator, "I#" is an Independent senator, and "R#" is a Republican/active 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.
