Colonia Dublán began as a Mormon colony, located in the state of Chihuahua, Mexico. It is now a part of Nuevo Casas Grandes Municipality. It is one of two surviving Mormon colonies in Mexico.

The Mormon colonies in Mexico are settlements located near the Sierra Madre mountains in northern Mexico which were established by members of the Church of Jesus Christ of Latter-day Saints beginning in 1885. The colonists came to Mexico due to federal attempts to curb and prosecute polygamy in the United States. Plural marriage, as polygamous relationships were called by church members, was an important tenet of the church—although it was never practiced by a majority of the membership.
