2022 Massachusetts House of Representatives election

The 2022 Massachusetts House of Representatives election was held on Tuesday, November 8, 2022, with the primary election having been held on Tuesday, September 6, 2022. Massachusetts voters selected all 160 members of the State House 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 Senate.

Democrats gained 9 seats, increasing their supermajority to 134 out of 160 seats, the largest majority of any party since 2009. Simultaneously with gains in the state Senate, 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.
