Radivoj of Bosnia (Serbo-Croatian: Radivoj Ostojić/Радивој Остојић; died in late May or early June 1463) was anti-king of Bosnia from 1432 until 1435, when he lost all control over the kingdom but did not relinquish the title, and again from 1443 until 1446, when he abandoned his claim. He was recognized as king by the Ottoman Empire and the Despotate of Serbia, as well as by the Bosnian noble houses of Kosača and Pavlović, but never by the West. Radivoj is thus seldom included in the list of rulers of Bosnia.
