The 2011 Wisconsin protests were a series of demonstrations in the state of Wisconsin in the United States beginning in February involving as many as 100,000 protesters opposing the 2011 Wisconsin Act 10, also called the "Wisconsin Budget Repair bill." The protests centered on the Wisconsin State Capitol in Madison, with satellite protests also occurring at other municipalities throughout the state. Demonstrations took place at various college campuses, including the University of Wisconsin–Madison and the University of Wisconsin–Milwaukee. After the collective bargaining bill was upheld by the Wisconsin Supreme Court on June 14, the number of protesters declined to about 1,000 within a couple days.

The Wisconsin State Capitol, located in Madison, Wisconsin, houses both chambers of the Wisconsin legislature along with the Wisconsin Supreme Court and the Office of the Governor. Completed in 1917, the building is the fifth to serve as the Wisconsin capitol since the first territorial legislature convened in 1836 and the third building since Wisconsin was granted statehood in 1848. The Wisconsin State Capitol is the tallest building in Madison, a distinction that has been preserved by legislation that prohibits buildings taller than the columns surrounding the dome. The Capitol is located at the southwestern end of the Madison Isthmus. The streets surrounding the building form the Capitol Square, which is home to many restaurants and shops.
