Antonio Gentile Pallavicini (Genoa, 1441 – 1507) was an Italian Cardinal. He was considered papabile in 1492. Bishop of Frascati from April until December 1503; later bishop of Palestrina.
He was bishop of Ventimiglia from 1484; then bishop of Ourense in Spain from 1486.</ref> From 1484 to 1489 he was Papal Datary in the Roman Curia, and therefore did not reside in Ventimiglia. In 1493, the pope Alexander VI appointed him bishop of Pamplona, taking over from Cesare Borgia, against the will of the monarchs of Navarre, and finding instead the veiled support of Ferdinand II of Aragon.
There is a well-known portrait by Titian. He was buried in the Old St. Peter's Basilica but his tomb was transferred to the Montemirabile Chapel in Santa Maria del Popolo in 1596.
Antonio's nephew was the cardinal Giovanni Battista Pallavicino (1480–1524).
