The Portrait of Isabella d'Este is a drawing (and possible painting) by Leonardo da Vinci which was executed between 1499 and 1500. It depicts Isabella d'Este, Marchioness of Mantua. During the Italian Wars of 1499–1504, the French invaded Italy which caused Leonardo to flee from Milan to Mantua. There he had met Isabella, where she commissioned her portrait from him.{{Cite web |title=Portrait of Isabella d'Este by Leonardo da Vinci |url=https://www.leonardo-da-vinci.net/portrait-of-isabella-d-este/ |access-date=18 August 2022 |website=www.leonardo-da-vinci.net}} Whether Leonardo completed the portrait is unknown. There is evidence through letters of the time that he held a fully completed painting of her, but they are vague in describing it. It is possible that the painting was lost to time or that it was, in fact, never completed at all. A version of the portrait in oils on canvas was found in a collection in Switzerland in 2015, but it has yet to be verified.{{Cite web |date=4 October 2013 |title=Leonardo da Vinci experts identify painting as lost Isabella D'Este portrait |url=http://www.theguardian.com/artanddesign/2013/oct/04/leonardo-da-vinci-lost-portrait-isabella-deste |access-date=18 August 2022 |website=The Guardian |language=en}}
