The 2026 United States Senate election in Massachusetts will be held on November 3, 2026, to elect a member of the United States Senate to represent the Commonwealth of Massachusetts. Incumbent two-term Democratic Senator Ed Markey, was re-elected in 2020 with 66.2% of the vote and is running for re-election to a third full term.

Markey, who will be 80 years old at the time of the 2026 election, has faced calls to retire due to his age.{{Cite web |last=Keller |first=Jon |date=2024-10-20 |title=Is it time for Ed Markey to step aside?
