2025 Wisconsin elections

The 2025 Wisconsin Spring Election was held in the U.S. state of Wisconsin on April 1, 2025. The race seen as most significant was an open seat on the Wisconsin Supreme Court, which became the most expensive judicial race in history. The election also included a state-wide race for Superintendent of Public Instruction. Several other nonpartisan local and judicial offices were also on the ballot, as were many local school funding referendums. The 2025 Wisconsin Spring Primary was held February 18, 2025.

The Democratic Party of Wisconsin was seen as broadly victorious across the state's Spring elections. In the Supreme Court race, the Democrats' preferred candidate, Susan M. Crawford, defeated the Republicans' preferred candidate, Brad Schimel, maintaining the liberal 4–3 majority on the court. The Democrats also supported the incumbent state superintendent, Jill Underly, who won a second four-year term. Additionally, Democrats saw success in many local elections including in emerging bellwether Winnebago County, where former Assembly minority leader Gordon Hintz defeated a Republican-backed incumbent to become county executive. Democrats also supported a number of successful school funding referendums throughout the state.

On the same ballot, however, voters ratified a Republican-supported amendment to the Constitution of Wisconsin, which enshrined a photo identification requirement to vote. The requirement was already in place in Wisconsin due to existing state laws; in effect, the amendment made the requirement harder to remove.
