Opizzo Fieschi (d. c. AD 1291), also known as Opizo or Opiso dei' Fieschi, was a 13th-century Italian cleric from the powerful Genovese Fieschi family. Following his uncle Sinibaldo's election as Pope Innocent IV, Opizzo was appointed the Catholic Church's patriarch of Antioch (probably in 1247 and possibly serving as long as the fall of Antioch in 1268).[3]
