Faustino Arévalo (23 July 1747 at Campanario, Badajoz in Extremadura, Spain – 7 January 1824 at Madrid) was a Spanish Jesuit hymnographer and patrologist. He entered the Society of Jesus in 1761, but was deported to Italy on the occasion of the deportation of the Jesuits from Spain (1767). There he won the esteem and confidence of Cardinal Lorenzana, who proved a patron for the young Spanish Jesuit, bore the expenses of his academic work, and made him his executor.
