The Andrew John Volstead House is the historic house in Granite Falls, Minnesota, of ten-term United States Congressman Andrew Volstead (1860–1947). It is now managed as a museum and the organizational headquarters of the Granite Falls Historical Society. Volstead became nationally synonymous with Prohibition in 1919 when, as chairman of the House Judiciary Committee, he was obliged to author the Volstead Act, enabling enforcement of the recently ratified Eighteenth Amendment. Volstead was a moderate progressive who coauthored the Capper–Volstead Act in 1922, which legalized agricultural cooperatives.
