Rostislav Mikhailovich (, Bulgarian and Ukrainian: Ростислав Михайлович) (after 1210 / c. 1225 – 1262) was a Rurikid prince 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.
Marriage and children In 1243, Rostislav married Anna of Hungary ( 1226 – after 1274), daughter of King Béla IV of Hungary and his wife, Maria Laskarina. Together they had the following children: Duke Michael of Bosnia (? – 1271) Duke Béla of Macsó (? – November, 1272) Unnamed daughter (perhaps Anna), wife firstly of Tsar Michael Asen I of Bulgaria, secondly of Tsar Koloman II of Bulgaria Kunigunda (1245 – September 9, 1285), wife firstly of King Ottokar II of Bohemia, and secondly of nobleman Záviš of Falkenštejn (Rosenberg) Agrippina (? – May 26, 1303/1309), wife of Prince Leszek II of Cracow
