Jaunutis (Belarusian: Яўнут; literally young man; baptized: Ioann,"Jawnuta", "John" or "Ivan"; ca. 1300 – after 1366) was the Grand Duke of Lithuania from his father Gediminas' death in 1341 until he was deposed by his elder brothers Algirdas and Kęstutis in 1345.
Jaunutis was not mentioned in any written sources prior to Gediminas' death.[1] There are many theories why Gediminas chose Jaunutis, a middle son, as his successor. Some suggested that he was an acceptable compromise between pagan (Algirdas and Kęstutis) and Orthodox (Narimantas, Karijotas, Liubartas) sons of Gediminas.[2] Others claimed that Jaunutis was the eldest son of Gediminas' second wife; thus the tradition that Gediminas was married twice: to a pagan and Orthodox duchess.[3]
