Johann Paul von Westhoff was a German Baroque composer and violinist. One of the most important exponents of the Dresden violin school, he was among the highest ranked violinists of his day, and composed some of the earliest known music for solo violin. He worked as musician and composer as a member of Dresden's Hofkapelle (1674–1697) and at the Weimar court (1699–1705), and was also active as a teacher of contemporary languages.
