Gerardo da Sesso (c. 1160 – 16 December 1211) was an Italian monk, bishop and cardinal of the Catholic Church. Gerardo came from a prominent Emilian family with Ghibelline leanings. He received a theological education, even penning a summa of his own, before joining the Cistercians. He was the abbot of Tiglieto from 1205 until 1209, bishop-elect of Novara from 1209 until his death and cardinal bishop-elect of Albano from April 1211 until his death. He was elected archbishop of Milan in 1211, but the election was irregular and he ignored it.
