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.
A regularly scheduled election for Superintendent of Public Instruction of Wisconsin was on the ballot for the general election on April 1, 2025. The incumbent superintendent Jill Underly, first elected in 2021, won her second four-year term, defeating education consultant Brittany Kinser.
Sauk County superintendent Jeff Wright also ran, but was eliminated in the February 18 nonpartisan primary.

A regularly scheduled Wisconsin Supreme Court election was on the ballot for the general election on April 1, 2025, for a ten-year term on the court. The incumbent judge, Ann Walsh Bradley, did not run for re-election, retiring after 30 years on the court. Dane County circuit judge Susan M. Crawford defeated Waukesha County circuit judge and former state attorney general Brad Schimel, maintaining the 4–3 liberal majority on the court.
The 2025 Wisconsin Supreme Court election became the most expensive judicial race in United States history, surpassing the 2023 Wisconsin Supreme Court election. Total spending on the race reached nearly $100 million; billionaire Elon Musk—at the time a senior advisor to U.S. President Donald Trump—spent more than $25 million through his political action committees on behalf of Brad Schimel.
