The Town of Duncan, population 800, straddles the storied Gila River in far southeastern Arizona, five miles from the New Mexico border. Surrounded by scenic mountains and historic mining sites, working ranches and lush farmlands, Duncan’s local businesses welcome visitors and help provide an experience of the Old West, much as it was a century before. Duncan is a fine rural setting for retirement, starting a small business or raising a family. The public schools are innovative and have won national awards. Come and enjoy our town, whether for an evening or a lifetime.
