Shemaryahu Yosef Chaim Kanievsky (Hebrew: שמריהו יוסף חיים קַניֶבסקִי; January 8, 1928 – March 18, 2022) was an Israeli Haredirabbi and posek.[2] He was a leading authority in Haredi Jewish society on legal and ethical practice.[3][4][5] Known as the Gadol HaDor ("greatest of his generation")[6] and the "Prince of Torah", much of his prominence came through Torah education and advice about Jewish law.[7][8]
Though Kanievsky held no formal community-wide post,[9] he was the de facto head of the Lithuanian branch of Haredi Judaism, revered as a consummate scholar of Jewish law and tradition, with unimpeachable rulings.[10]
