Ottavio Gaetani (22 April 1566 - 8 March 1620) was an Italian Jesuit and historian, writing exclusively in Latin and most notable for his Vitae Sanctorum Siculorum. He is held to be the founder of hagiography in his native Sicily and one of the island's main 16th-century and early 17th-century historians.
