Stefano de Normandis dei Conti (Rome or Perugia, circa 1190 – Naples, 8 December 1254) was an Italian cardinal. He was a nephew of Pope Innocent III.
Belonging to a family of ancient nobility, he dedicated himself to an ecclesiastical career after the death of his wife, having already had a son Filippo who joined the Franciscan Order. In 1216 Stefano was appointed cardinal deacon of Sant'Adriano al Foro by Pope Innocent III, of whom he was a nephew. In 1228 he was translated to the title of cardinal priest of Santa Maria in Trastevere and in 1231 he was appointed Archpriest of the Vatican Basilica. He also received prebends of Lyme & Halstock (Salisbury), Lincoln, and York.[1] After Pope Innocent IV had fled Rome for Lyon during his confrontation with Emperor Frederick II, Conti became Cardinal Vicar of Rome from 1244 to 1251. In 1245 he became the Protopriest of the College of Cardinals. At the request of the pope, he reduced the number of canonics from 36 to 25 and reformed the chapter of the Lateran Basilica.[2] Conti served as papal legate in the Kingdom of Sicily where he pronounced papal deposition of Frederick.[2] He then served as governor of the provinces of Sabina and Campagna e Marittima of the Papal States.[2] He built and decorated the chapel of St. Sylvester at the church of Santi Quattro Coronati. He died in Naples on 8 December 1254, the last of the cardinals of Innocent III, and was buried in the city's cathedral.
