To secure a relationship with the powerful Roman Orsinis, Isabella's father arranged her marriage to Paolo Giordano I Orsini when she was 16. She remained in her father's household after her marriage, giving her an unusual degree of independence for a woman of her period. Following the death of her father, Isabella was murdered, with the complicity of her husband and brother, and in retribution for her relationship with Paolo Giordano's cousin Troilo Orsini.

. The two married in 1558, in a semi-private ceremony, at Villa di Castello. Paolo left the following day. Concerned by the spending habits of his new son-in-law, Cosimo decided to keep his daughter and her 50,000 scudi dowry in Florence, giving her greater freedom and control over her own affairs than was customary for Florentine women of the time. Following her mother's death, she acted as first lady of Florence for a time, displaying the de' Medici aptitude for politics. She suffered several miscarriages and remained childless until her late twenties. Her daughter Francesca Eleonora (known as Nora), was born in 1571 and eventually married her cousin Alessandro Sforza. Her son Virginio was born in 1572 and eventually inherited his father's dukedom. Isabella's free-spirited personality created rumours with regard to the nature of her relationship with Troilo Orsini, Paolo Giordano's cousin, who was charged with looking after her while her husband tended to military duties. On 16 July 1576 Isabella died unexpectedly at the Medici villa in Cerreto Guidi during a hunting holiday. According to her brother, the grandduke, this occurred "while she was washing her hair in the morning ... She was found by Signor Paolo Giordano on her knees, having immediately fallen dead." However, the official version of events was not generally believed, and the Ferrarese ambassador, Ercole Cortile, obtained information that Isabella was "strangled at midday" by her husband in the presence of several named servants. Isabella was the second sudden death in an isolated country villa in the Medici family: her cousin Leonora died of a similar "accident" only a few days before, but she was actually murdered on the orders of her husband, Pietro de' Medici. Most contemporary observers and modern historians assume that Paolo Giordano killed Isabella, in reprisal for carrying on a love affair with Troilo Orsini, or that he acted on instructions of the Grandduke Francesco, Isabella's brother.
