Giovanni Borgia, 2nd Duke of Gandía (1474 or 1476–1497) was the son of Pope Alexander VI and a member of the House of Borgia. He was murdered in 1497. He was the brother of Cesare, Gioffre, and Lucrezia Borgia. Giovanni, commonly known as Juan (or sometimes, Joan), is believed to be the eldest of the Pope's four children by Vannozza dei Cattanei, but this is disputed. Due to the contents of a number of papal bulls issued after his murder, it is unclear whether Giovanni was born in 1474 or 1476.
