Potosi is a village in Grant County, Wisconsin, United States.

Potosi is located where Wisconsin's lead ore belt intersects with the Mississippi.

30.8% of all households were made up of individuals, and 18.2% had someone living alone who was 65 years of age or older.

The Potosi Brewery in the village operated from 1852 to 1972, and reopened in 2008 following a restoration project which converted the facility into a museum and brew pub.

The event includes a truck and tractor pull, beanbag and a euchre tournament, fireworks, live music, a parade, and the fish fry.

The museum features historic beer and brewing memorabilia, including signs, advertisements, bottles, cans, and miscellaneous paraphernalia.

[13] Current maps show a three-mile stretch, with numerous streets—including one named "Cross Street"—that drain into it and end, forming T-shaped intersections, but no street that continues across it.

The Potosi Badger Huts Site, remnants of the region's lead mining history, are listed on the National Register of Historic Places and accessible by trail.
