Luis de Carvajal was a Spanish Franciscan theologian of the Council of Trent.
Of the noble family of Carvajal in Baetica, Carvajal at an early age was sent to the University of Paris, where he completed his studies. Having entered the Franciscan Order, he taught theology at Paris, whence he was sent as legate of Cardinal Angelus to the Council of Trent.
