Hendrik Godfried Duurkoop (5 May 1736, Dornum – 27 July 1778, at sea) was a Dutch merchant-trader and VOC Opperhoofd in Japan.
During his career with the Dutch East Indies Company (the Verenigde Oost-Indische Compagnie or VOC), he worked on Dejima, a small artificial island in the harbor of Nagasaki, Japan.
Duurkoop took up his duties as Opperhoofd or chief negotiant in November 1776.
During his stay in Batavia, he was infected with malaria; he died on board the ship "Huis ter Spijk" en route back to Japan in 1778.
[3] His death meant that Arend Willem Feith could not be relieved of his duties as Opperhoofd at Dejima for yet another year when Isaac Titsingh would eventually arrive in 1779.
