Fray José Servando Teresa de Mier Noriega y Guerra (October 18, 1765 – December 3, 1827) was a Roman Catholic priest, preacher, and politician in New Spain. He was imprisoned several times for his controversial beliefs, and lived in exile in Spain, France and England. His sermons and writings presented revisionist theological and historical opinions that supported republicanism. Mier worked with Francisco Javier Mina during the Mexican War of Independence and, as a deputy in independent Mexico's constituent Congress, opposed Agustín de Iturbide's claim to imperial rule. He is honored for his role in Mexican independence.
