Jean-Marie (Jean) Dutertre (1768, Lorient - 1811) was a French privateer. His ships included the Modeste, the Heureux, the Passe-Partout and the Malartic.
He was a friend and rival to Robert Surcouf in the Indian Ocean, one of whose several captured East Indiamen was carrying the theodolite which would be used to triangulate the Indies then measure the height of Mount Everest - this was returned "with compliments, for science". His dispute over recruiting crews at Port Louis on Mauritius - lured by a "better diet on board" - was settled by governor Malartic.
He was finally captured by the British and imprisoned in London until his release under the 1803 Treaty of Amiens. He later became lieutenant in the French Navy after the Bourbon Restoration.
