Mstislav Vladimirovich[a] (died c. 1035) was the earliest attested prince of Tmutarakan and Chernigov in Kievan Rus'. He was a younger son of Vladimir the Great, the grand prince of Kiev. His father appointed him to rule Tmutarakan, an important fortress by the Strait of Kerch, in or after 988.
He invaded the core territories of Kievan Rus', which were ruled by his brother, Yaroslav the Wise, in 1024. Although Mstislav could not take Kiev, he forced the East Slavic tribes dwelling to the east of the Dniester River to accept his suzerainty. Yaroslav the Wise also accepted the division of Kievan Rus' along the river after Mstislav had defeated him in a battle fought at Listven by Chernigov. Mstislav transferred his seat to the latter town, and became the first ruler of the principality emerging around it.
