2026 Wisconsin Senate election
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 previous legislative district map to be unconstitutional on December 22, 2023.
