Jean Godin des Odonais (5 July 1713 Saint-Amand-Montrond, France - 1 March 1792 Paris) was a French cartographer and naturalist.
Godin des Odonais had joined the world's first geodesy expedition to the equator, led by Charles Marie de La Condamine.
When the commission returned to France, Godin des Odonais became professor of astronomy and natural science at the College of Quito, 1739.
Having lost the greater part of his wife's dowry in speculations, he resolved to try his fortune in Cayenne, where he arrived in May, 1750, and settled on the banks of the river Oyapok.
In 1784 he was elected a member of the French Academy of Science, and he labored thenceforth to arrange the notes taken during the many years of his explorations.
