John Willett Payne (23 April 1752 – 17 November 1803) was an officer of the Royal Navy who also served as a close friend, advisor and courtier to Prince George before and during his first regency. Payne was notorious as a rake and scoundrel, but was also a Member of Parliament and noted for his bravery in several military actions during the American Revolutionary War and the French Revolutionary Wars. Out of favour in his later years, Payne was reconciled with the Prince in 1799, but died whilst still in the service aged 51, from an illness which developed during blockade operations in the Western Approaches.
