Moses Margoliouth (1820–1881) was a Polish-born British scholar and Jewish convert to Christianity. He became a minister in the Church of England. Alongside Elieser Bassin, he was also one of the first proponents of British Israelism to be of Jewish descent. He published History of the Jews in Great Britain (1851) and Vestiges of the Historic Anglo-Hebrews in East Anglia (1870). His nephew was David Samuel Margoliouth.
