2026 U.S. Senate election in Massachusetts

Election: 11/3/2026
United States Senate • Massachusetts
Updated: 4/6/2026

Massachusetts will elect one U.S. senator in 2026 for the state’s Class II seat. The race matters because it will determine whether incumbent Democrat Ed Markey wins another term and because the seat is part of the broader balance of power in the U.S. Senate. Massachusetts is a strongly Democratic state in federal elections, so the main competition is expected to be in the Democratic primary, where Markey faces challengers including Rep. Seth Moulton. The race has centered on generational change, Markey’s long record in Congress, and contrasting views on how aggressively Democrats should confront national politics and policy priorities.
