Colonia Díaz was the first permanent Mormon colony in Mexico, located along the Casas Grandes River in the northeast of the state of Chihuahua, Mexico. It is now a ghost town bordered on the east by the Sierra Madre Occidental. It was the nearest colony to the Mexico–United States border. By 1900, Díaz had grown to 623 inhabitants. In 1912, during the Mexican revolution, Colonia Díaz was intentionally burned and destroyed. Other neighboring colonies were established after Colonia Díaz in the late 19th century, of which only Colonia Dublán, sixty miles south of Colonia Díaz, and Colonia Juárez, 18 miles southeast of Colonia Dublán, are still inhabited.
