Annibale Gaetani di Ceccano (c. 1282 – 1350) was an Italian Cardinal. His palace, the Livrée Ceccano at Avignon, begun in about 1335/1340, still survives; it is now a public library.
He was Archbishop of Naples from 1326 to 1328 and undertook diplomatic missions, for example setting up the 1343 truce between England and France. He was Bishop of Frascati from 1332 to 1350. He was Archdeacon of Cornwall from 1342 to 1344, and Archdeacon of Nottingham from 1331 - 1348.
He is celebrated for the luxury of a feast he gave in 1343 for Pope Clement VI, an eye-witness account of which has survived.
