Johann Philipp von Hattorf (6 March 1682 – 3 September 1737) was a Hanoverianminister and head of the German Chancery in London from 1723 until 1737. He was the son of Johann von Hattorf and Anna Mülle, and married Marie Margarethe von Molan on 29 July 1705. Hattorf was one of fifteen ministers and advisers who came to Great Britain with George I in 1714. From that year until 1723, he served as secretary of the German Chancery with Andreas Gottlieb von Bernstorff as head. In July 1719, Hattorf and Northern SecretaryJames Stanhope, 1st Earl Stanhope, pushed Bernstorff out of office, leaving Hanoverian politics to fall into the hands of British ministers.Hans Caspar von Bothmer took over as de facto head of the Chancery in 1720 until Bernstorff formally retired in 1723. From that time on, Hattorf was the official Chancery office head, although Bothmer continued in his role as unofficial head until his own death in 1732. Unlike his predecessor, Hattorf lacked political confidence during the reigns of George I and George II and died quietly in 1837 at Hampton Court, being succeeded in his role by Ernst von Steinberg. He left behind one daughter, Johanne Louise.
