Franceschetto Cybo (baptized Francesco) (c. 1450 – July 25, 1519) was an Italian nobleman, noteworthy for being the illegitimate son of Pope Innocent VIII (Giovanni Battista Cybo). Later naturalized by his father into becoming his legitimate heir, Franceschetto was infamous for his gambling addiction and wanton spending of the Papal treasury for various pleasures and scandals. He is otherwise noteworthy for his political marriage to Maddalena de Medici, and their offspring formed a dynastic lineage that persists in the nobility of Europe until today.

Early life 
Franceschetto was born in Naples in 1450, to an unknown Neapolitan woman and Giovanni Battista Cybo. His father would later be elected Pope and take the name Innocent VIII. Although born with the name Francesco, he was nicknamed "Franceschetto" due to his short size. Upon his father's ascenscion to the Papacy as Pope Innocent VIII, Franceschetto infamously engaged in rampant gambling and womanizing throughout Rome. After failed attempts at marriage with one of the bastard daughters of the King of Naples, Franceschetto was eventually married to Lorenzo de' Medici's daughter, Maddalena de' Medici. This was part of a deal between Pope Innocent VIII and Lorenzo, where the Pope would make Giovanni de Medici, Lorenzo's son, into a cardinal in exchange for this marriage to Maddalena. Through this marriage and deal, therefore, Franceschetto was brother-in-law to Pope Leo X (Giovanni de' Medici).

Noble career 
Despite his infamy and the numerous scandals surrounding him, Franceschetto received from his father important positions in the Papal States: governor and Captain General of Rome (1488), the fiefs of Cerveteri and Anguillara (1490) and the title of Count of the Lateran Palace, among others.

In September 1490, amidst false rumors of the death of Innocent VIII, Franceschetto attempted to seize the Papal treasury and also kidnapped son of Sultan Mehmed II, Cem, in an attempt to extract ransom money. This failed when the Pope turned out to be alive, but a significant portion of the treasury remained missing even afterwards.

Two years later, after Innocent VIII's death, Franceschetto was forced into hiding with the election of Pope Alexander VI, who looked poorly upon Franceschetto's Medici and Orsini allies. Franceschetto was forced to sell many of his father's possessions, including the title of count of Anguillara, while moving between various cities in Italy. He eventually could return to Rome thanks to the election of the more favourable Pope Julius II (1503), who gave him the title of Duke of Spoleto.

Franceschetto's lot continued to improve with the election of his brother-in-law Giovanni de Medici to the papacy as Pope Leo X, who also gave him several titles, and eventually made Franceschetto's son Innocenzo into a cardinal.

Death 
He died in 1519 after a trip to Tunis. He is buried in Innocent VIII's sepulchre in St. Peter's Basilica.
