Antonio Maria Ciocchi del Monte (died 20 September, 1533) was an Italian Roman Catholic bishop and cardinal.
Antonio Maria Ciocchi del Monte was born in Monte San Savino sometime between late September 1461 and early September 1462. He was the son of Fabiano Ciocchi and Jacopa, daughter of Gaspare, whose last name is not known. His father dropped the surname "Ciocchi" taking "del Monte San Savino" as his surname (soon shortened to "del Monte"). Antonio Maria Ciocchi del Monte was the uncle of Pope Julius III.
As a young man, Ciocchi del Monte became a doctor of both laws. He then joined his older brother in Rome. He was soon appointed a consistorial advocate by the Roman Curia. His legal talents brought him to the attention of Pope Innocent VIII, who considered him a valuable advisor. Innocent VIII made him archpriest of Sant'Angelo in Vado, and, in 1492, archpriest of Arezzo.
Ciocchi del Monte also found favor with Pope Alexander VI. On March 27, 1493, Alexander VI made him an auditor of the Roman Rota. In 1495, he was made rector of Sant'Agnese in Arezzo, and in 1496, provost of San Luciano near Monte San Savino. After spending time attending to his pastoral duties, he was recalled to Rome in 1498 and placed in charge of the daily operations of the Roman Rota. In July 1502, the pope put him in charge of all operations of the Roman Rota in the areas under the control of the pope's son, Cesare Borgia. He set up a judicial seat in Cesena. He was also made a protonotary apostolic at this time. In early 1503, Cesare Borgia elevated Ciocchi del Monte to the post of governor of Romagna.
