Count Gustaf Philip Creutz (Swedish pronunciation: [ˈɡɵsːtaf ˈfiːlɪp ˈkrœɪts]; 1 May 1731 in Anjala, Finland – 30 October 1785 in ), was a Swedish statesman, diplomat and poet.
Creutz was born in Finland and after concluding his studies at the Royal Academy of Turku he received a post in the Privy Council Chancery at in 1751. Here he met Count Gustaf Fredrik Gyllenborg, with whom his name is indissolubly connected. They were closely allied with Hedvig Charlotta Nordenflycht, and their works were published in common; to their own generation they seemed equal in fame, but posterity has given the palm of genius to Creutz.
His greatest work is contained in the 1762 volume, the idyll of Atis och Camilla; the exquisite little pastoral entitled Daphne was published at the same time, and Gyllenborg was the first to proclaim the supremacy of his friend.
In 1763 Creutz practically closed his poetical career; he went to Spain as ambassador, and after three years to Paris in the same capacity until May 1783, and it was during this time that Creutz met with the American resident in Paris at the time, Benjamin Franklin. Creutz and Franklin drafted the first Treaty of Amity and Commerce between the two nations.
In 1783 King Gustav III of Sweden recalled him and heaped honours upon him, but he died soon after. In 1784, he was elected a member of the Royal Swedish Academy of Sciences.
