Faustino Arévalo (23 July 1747 at Campanario, Badajoz in Extremadura, Spain – 7 January 1824 at Madrid) was a Spanish Jesuit hymnographer and patrologist.
There he won the esteem and confidence of Francisco Antonio de Lorenzana, who proved a patron for the young Spanish Jesuit, bore the expenses of his academic work, and made him his executor.
[1] Arévalo held various offices of trust in Rome, among them that of "pontifical hymnographer".
He was made theologian of the Apostolic Penitentiary in 1809, in succession to Alfonso Muzzarelli.
In 1815 he returned to Spain, recalled by King Ferdinand, entered the restored Society, and became provincial of Castile (1820).
