Sir Paul Rycaut FRS (23 December 1629 London – 16 November 1700 Hamburg) was a British diplomat and historian, and authority on the Ottoman Empire.

While studying at Alcalá de Henares, he learned Spanish and translated the first part of Baltasar Gracián's The Critick. Rycaut was then employed as private secretary to Heneage Finch, 3rd Earl of Winchilsea, ambassador to Constantinople. He became British Consul and factor at Smyrna. From 1689 to 1700, he was Resident at Hamburg.
On 12 December 1666, Rycaut was elected a Fellow of the Royal Society.
