Yaroslav Vasilkovich of Vitebsk

Yaroslav Vasilkovich is a putative prince named in the Genealogy of the Princes of Vitebsk as the last appanage prince of Vitebsk, who died in 1320. The chronicle, compiled no earlier than the sixteenth century, relates that he had no sons and in 1318 married his daughter Maria to the Lithuanian prince Algirdas.

The marriage legitimized Lithuanian rule over Vitebsk. The principality gradually lost its independence and in 1393 became the Vitebsk Voivodeship of the Grand Duchy of Lithuania.
