Ottokar II (; , in Městec Králové, Bohemia – 26 August 1278, in Dürnkrut, Lower Austria), the Iron and Golden King, was a member of the Přemyslid dynasty who reigned as King of Bohemia from 1253 until his death in 1278. He also held the titles of Margrave of Moravia from 1247, Duke of Austria from 1251, and Duke of Styria from 1260, as well as Duke of Carinthia and landgrave of Carniola from 1269. With Ottokar's rule, the Přemyslids reached the peak of their power in the Holy Roman Empire. His expectations of the imperial crown, however, were never fulfilled. Ottokar was the second son of King Wenceslaus I of Bohemia (reigned 1230–1253). Through his mother, Kunigunde, daughter of Philip of Swabia, he was related to the Holy Roman Emperors of the Hohenstaufen dynasty, which became extinct in the male line upon the execution of King Conradin of Sicily in 1268. Named after his grandfather King Přemysl Ottokar I, he was originally educated for the role of an ecclesiastical administrator, while his elder brother Vladislaus was designated heir of the Bohemian kingdom. He was possibly educated by the Bohemian chancellor Philip of Spanheim, who would later become a rival for the rule of the Duchy of Carinthia.

His father appointed the new heir as Margrave of Moravia, and Ottokar took up residence in Brno, where he was occupied with the reconstruction of the Moravian lands devastated by Mongol raids of 1242. In 1248, some discontented nobles enticed him into leading a rebellion against his father King Wenceslaus. During this rebellion he was elected "the younger King" (mladší král) on 31 July 1248 and temporarily expelled his father from Prague Castle. Přemysl Ottokar II held the title of King of Bohemia until November 1249. However, Pope Innocent IV excommunicated Ottokar, whereafter Wenceslaus finally managed to defeat the rebels and imprisoned his son at Přimda Castle. Father and son eventually reconciled to assist the king's aim of acquiring the neighbouring Duchy of Austria, where the last Babenberg duke, Frederick II had been killed in the 1246 Battle of the Leitha River.
