The 2011 Wisconsin Supreme Court election took place on Tuesday, April 5, 2011. The incumbent justice, David Prosser Jr., was re-elected to another ten-year term, defeating assistant attorney general JoAnne Kloppenburg. Unlike past elections for the Wisconsin Supreme Court, the race gained significant nationwide publicity as it was widely seen as the first referendum on Wisconsin Governor Scott Walker's proposed anti-union legislation and the resulting protests.
