The 2026 Massachusetts Senate election will be held on November 3, 2026, alongside the other 2026 United States elections. Primary elections will be held on September 1, 2026. Voters will elect members of the Massachusetts Senate in all 40 of the U.S. state of Massachusetts's legislative districts to serve a two-year term. The election will coincide with United States national elections and Massachusetts state elections, including U.S. Senate, U.S. House, Governor, and Massachusetts House.

Democrats won 35 seats in 2024. This fell to 34 after state senator Ed Kennedy died in October 2025. He was replaced in a special election by fellow Democrat Vanna Howard, bringing Democrats back to 35 seats. Republicans would need to net 16 seats to flip control of the chamber. However, Republicans are leaving 29 seats—a majority—uncontested.

2026 special election: 1st Middlesex A special election in the 1st Middlesex district was called after Democratic senator Ed Kennedy died in October 2025. The election was won by Democratic state representative Vanna Howard.
