Solomon Ayllon (1660 or 1664 – April 10, 1728) was haham of the Sephardic congregations in London and Amsterdam, and a follower of Shabbethai Ẓebi. His name is derived from the town of Ayllon, in what is now the province of Segovia. Ayllon was neither a general scholar nor a Talmudist of standing, but his history is closely interwoven with that of Sabbateanism in both the East and the West. Ayllon left a cabalistic work, a manuscript of which is preserved in the library of the Jews' College in London.
