Filadelfo Mugnos (1607 – May 28, 1675) was an Italian historian, genealogist, poet and man of letters.
He was born in Sicily at Lentini in 1607, but moved while young to Palermo. He obtained a doctorate in Law at the University of Catania. He was made a member of the Portuguese chivalric Order of Christ and of various learned academies of the day.
