Elżbieta "Izabela" Dorota Czartoryska was a Polish princess, writer, art collector, and prominent figure in the Polish Enlightenment. She was the wife of Adam Kazimierz Czartoryski and a member of the influential Familia political party. She is also known for having founded Poland's first museum, the Czartoryski Museum, now located in Kraków.

The House of Czartoryski is a Polish princely family of Lithuanian-Ruthenian origin, also known as the Familia. The family, which derived their kin from the Gediminids dynasty, by the mid-17th century had split into two branches, based in the Klevan Castle and the Korets Castle, respectively. They used the Czartoryski coat of arms and were a noble family of the Polish–Lithuanian Commonwealth in the 18th century.
