Jean d'Espagnet (1564 - c. 1637) was a French lawyer and politician, and writer on alchemy. In 1601 he became President of the Parlement of Bordeaux. In this position he was involved, with Pierre de Lancre, in witch-hunting in Labourd. D'Espagnet contributed to de Lancre's 1607 work on witchcraft.
He is known for the 1623 books Arcanum Hermeticae philosophiae and Enchiridion physicae restitutae.[1]
