Giambattista Orsini

Giambattista Orsini (died February 22, 1503) (also called Giovanni Battista Orsini or Jean-Baptiste des Ursins) was an Italian Roman Catholic cardinal.

Giambattista Orsini was born in Rome before 1450, the son of Lorenzo Orsini, signore of Monte Rotondo, and Clarice Orsini, sister of Cardinal Latino Orsini.

Early in his career, he became a cleric of the Apostolic Camera. He was next an Auditor of the Roman Rota. He was a canon of St. Peter's Basilica. Finally, he became a protonotary apostolic.

In the consistory of November 15, 1483, Pope Sixtus IV made him a cardinal deacon and he received the deaconry of Santa Maria in Domnica. He received the red hat on November 19, 1483.

He participated in the papal conclave of 1484 that elected Pope Innocent VIII. The new pope named Cardinal Orsini papal legate to the March of Ancona on September 22, 1484.

In 1486, because of the conflict between the pope and the Orsini family, he traveled to Rome to attempt to effect a reconciliation, but left a short time later.
