town, southwest Bolivia. It lies in an Andean region at an elevation of 9,800 feet (2,990 metres) about 130 miles (210 km) west of Tarija. Once a thriving mining centre, Tupiza is mainly a commercial and trade hub; however, some nearby mining operations remained after the collapse of tin prices in the mid-1980s. Tupiza is near the town of San Vicente, close to which American outlaws Butch Cassidy and the Sundance Kid were said to have been gunned down by Bolivian troops. Pop. (2001) 21,707.
