Rostislav Mikhailovich (Hungarian: Rosztyiszláv,Bulgarian and Russian: Ростислав Михайлович) (after 1210 / c. 1225 – 1262) was a Rus' prince (a member of the Rurik dynasty), and a dignitary in the Kingdom of Hungary.
He was prince of Novgorod (1230), of Halych (1236–1237, 1241–1242), of Lutsk (1240), and of Chernigov (1241–1242). When he could not strengthen his rule in Halych, he went to the court of King Béla IV of Hungary, and married the king's daughter, Anna.
He was the Ban of Slavonia (1247–1248), and later he became the first Duke of Macsó (after 1248–1262), and thus he governed the southern parts of the kingdom. In 1257, he occupied Vidin and thenceforward he styled himself Tsar of Bulgaria.
Rostislav was the eldest son of Prince Mikhail Vsevolodovich (who may have been either prince of Pereyaslavl or Chernigov when Rostislav was born) and his wife Elena Romanovna (or Maria Romanovna), a daughter of Roman Mstislavich, prince of Volhynia and Halych. The Russian annals mentioned him for the first time in 1229 when the Novgorodians invited his father to be their prince.
Rostislav underwent the ritual hair-cutting ceremony (postrig) in the Saint Sophia Cathedral in Novgorod on May 19, 1230, and his father installed him on the throne. The postrig conferred on Rostislav the official status of prince of Novgorod and thus he ruled Novgorod as a fully fledged prince after the ceremony. Rostislav, in keeping with his father’s policy, continued to pass legislation favoring the Novgorodians.
