As of April 2024, no Republican or Democratic senators have announced plans for retirement; two Republican senators and five Democratic senators are running for re-election.

This will be the first Senate election since 2006 in which the Republican Party will not be led by Mitch McConnell.

All 33 Class 2 Senate 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. This is also the first cycle since 2014 that Arizona will not have a US Senate election.

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.
