Nehemiah Hiyya ben Moses Hayyun (ca. 1650 – ca. 1730) was a Bosnian Kabalist, described by scholars as linked to Sabbateanism.[1][2] His parents, of Sephardic descent, lived in Sarajevo, Bosnia (then a part of the Ottoman Empire), where he was most likely born, though later in life he pretended that he was a Palestinian emissary born in Safed. He received his Talmudic education in Hebron.
