2022 Massachusetts Senate election

The 2022 Massachusetts State Senate election was held on Tuesday, November 8, 2022, with the primary election having been held on Tuesday, September 6, 2022. Massachusetts voters selected all 40 members of the State Senate to serve two-year terms in the 2023–2024 Massachusetts legislature. The election coincided with United States national elections and Massachusetts state elections, including U.S. House, Governor, and Massachusetts House.

Democrats gained 1 seat, increasing their supermajority to 37 out of 40 seats. Simultaneously with gains in the state House, and Maura Healey's win in the gubernatorial race, Democrats won a trifecta in the state for the first time since 2014.

These were the first elections in Massachusetts following the 2020 United States redistricting cycle, which resulted in some members being assigned to new districts.
