Old Mines (French: La Vieille Mine) is the name of an unincorporated community and surrounding area in southeast Missouri that were settled by French colonists in the early 18th century when the area was part of the Illinois Country of New France. The early settlers came to mine for lead, and their descendants still inhabit the area where, through a combination of geographic and cultural isolation, they maintained a distinctive French culture well into the 20th century. As recently as the late 1980s there may have been a thousand native speakers of the region's Missouri French dialect. This culturally distinct population has sometimes been referred to as "paw-paw French" and lives in an amorphous area in Washington, Jefferson, and St. Francois counties roughly 15 miles (24 km) either side of a line from Potosi to De Soto.
