Daniel S. Zion (3 August 1883, Salonica – 13 November 1979, Jaffa) was an Orthodox rabbi, Kabbalist and political activist. Zion moved to Sofia, Bulgaria, as a slaughterer and cantor. Bulgaria's Jewish community at the time was almost completely assimilated, and there were no ultra-Orthodox communities in the country during World War II. In 1943, Zion was removed from his position on the local rabbinic court for his newfound belief that Jesus of Nazareth was the Jewish Messiah.
