Elizabeth of Lithuania (Elżbieta Giedyminówna)

Elizabeth Giedyminówna (c. 1301–1364) was a Lithuanian princess, the daughter of Grand Duke Gediminas. Around 1316 she married Wenceslaus, the Piast duke of Płock, and bore him two children, Anna and Bolesław III. After Wenceslaus died in 1336, she probably served as regent for her minor son until he came of age around 1340–1343.

In 1349 Bolesław granted her Wyszogród for life. She died on 2 June 1364 and was buried in Płock Cathedral.
