The 2026 Wisconsin Senate election is scheduled to be held on Tuesday, November 3, 2026. Seventeen of the 33 seats in the Wisconsin Senate are up for election—the odd-numbered districts.
This election will be significantly affected by the legislative maps drawn as a result of the Wisconsin Supreme Court decision in Clarke v. Wisconsin Elections Commission, which declared the current legislative district map to be unconstitutional on December 22, 2023. The court was in the process of selecting a remedial plan, when the legislature chose to embrace the remedial map proposal from Governor Tony Evers. Evers signed the plan into law on February 19, 2024.[1]
Under the new maps, control of the Senate could go to either party thanks to Democratic gains in the 2024 Wisconsin Senate election.[2]
