Jewna (, , literally, young woman; died ca. 1344) was daughter of Prince Ivan of Polatsk and wife of Gediminas, the Grand Duke of Lithuania, Ruthenia and Samogitia (1316–1341). She is mentioned in written sources only once – the Bychowiec Chronicle, a late and unreliable source. Therefore some historians cast a serious doubt on her existence, but modern reference works still widely cite her as the ancestress of the Gediminids dynasty.
