The Basilica of San Albino, formerly known as San Albino Church of Mesilla, is part of the Roman Catholic Diocese of Las Cruces and is located in Mesilla, New Mexico. It has the distinction of having originally been established in Mexico, but it is now located in the United States as a result of a transfer of territory in the Gadsden Purchase. The first church on the site was built in 1852; the current structure was built in 1906, and is one of the oldest churches in the region.
