Redistricting in Wisconsin is the process by which boundaries are redrawn for municipal wards, Wisconsin State Assembly districts, Wisconsin State Senate districts, and Wisconsin's congressional districts. Redistricting typically occurs—as in other U.S. states—once every decade, usually in the year after the decennial United States census. According to the Wisconsin Constitution, redistricting in Wisconsin follows the regular legislative process, it must be passed by both houses of the Wisconsin Legislature and signed by the Governor of Wisconsin—unless the Legislature has sufficient votes to override a gubernatorial veto. Due to political gridlock, however, it has become common for Wisconsin redistricting to be conducted by courts. The 1982, 1992, and 2002 legislative maps were each enacted by panels of United States federal judges; the 1964 and 2022 maps were enacted by the Wisconsin Supreme Court.
The most recent legislative redistricting occurred in February 2024, when governor Tony Evers signed 2023 Wisconsin Act 94. This followed a 2023 decision by the Wisconsin Supreme Court to strike down the previous legislative maps, ending 12 years of extreme partisan gerrymandering in Wisconsin.
The congressional maps were last set in April 2022, when the Wisconsin Supreme Court selected a map in the Johnson v. Wisconsin Elections Commission lawsuit, with only minor changes from the map passed by the legislature 10 years earlier.
