Yaroslav Osmomysl (Ukrainian: Ярослав Осмомисл, Yaroslav Volodymyrkovych Osmomysl) (ca. 1135 – 1 October 1187) was the most famous Prince of Halych (now in Western Ukraine) from the first dynasty of its rulers, which descended from Yaroslav I's eldest son. His sobriquet, meaning "Eight-Minded" in Old East Slavic, was granted to him in recognition of his wisdom. Some scholars even assert that Yaroslav was fluent in eight foreign languages.
