Dalmacio de Mur y de Cervelló (died 12 September 1456) was a Spanish prelate of the fifteenth century. He served as Bishop of Girona (1415-1418), Bishop of Tarragona (1419-31), and finally Archbishop of Zaragoza (1431-56).
Dalmacio de Mur y Cervelló was born at Cervera. He was a patron of the arts, embellishing with Gothic art the churches he served in. In 1426 he commissioned from the sculptor Pere Johan (active 1418-58) the alabaster and wood retablo that still dominates the Cathedral of Tarragona. He was buried in the La Seo Cathedral of Zaragoza.
