The 2020 Massachusetts Senate election was held on November 3, 2020 to elect all 40 members of the Massachusetts Senate. Primary elections were held on September 1, 2020. Voters in Massachusetts elected all 40 members of the State Senate to serve two-year terms in the Massachusetts General Court. The election coincided with United States national elections and Massachusetts state elections, including U.S. Senate, U.S. House, U.S. President, and Massachusetts House.
Democrats started the 2019 legislative session with 34 seats. However, after two Republican senators resigned to take other roles, special elections were held in which Democrats flipped both seats, bringing the Democratic caucus to 36 members and leaving Republicans with just 4 senators.
Democrats flipped a third seat on election day with Democrat John Cronin defeating incumbent Republican Dean Tran. Republicans held only 3 seats after the elections.
