Slinger is a village in Washington County, Wisconsin, United States. The population was 3,901 at the 2000 census.
Originally named Schleisingerville after the founder, state senator Baruch Schleisinger (Weil) in 1857, it was shortened during the 1920s to Slinger, a nickname which was already in common usage by the area residents. An incorrect legend has it that the name was shortened due to anti-German feeling following World War I. In fact, B.S. Weil immigrated from France, not Germany, while the population of Slinger itself was of predominantly German ancestry at the time of the name change.
