Potosi is a city in Washington County, Missouri, United States. Potosi is seventy-two miles southwest of St. Louis. The population was 2,538 as of the 2020 census. It is the county seat of Washington County.[4]

Located in the Lead Belt, the city was founded in 1763 by French colonists as Mine à Breton or Mine au Breton. After the United States acquired this area, American Moses Austin renamed the community for the Bolivian silver-mining city of Potosí. He was involved in lead mining. [5]
