Philippe Gengembre (born March 22, 1764 in Houdain , † January 19, 1838 in Indre (Loire-Atlantique) ) was a French chemist. Under Napoleon he was inspector general for money.

Gengembre was a student of Antoine de Lavoisier and assisted him and Pierre-Simon de Laplace, among other things, in their experiments on thermodynamics. From 1791 to 1794 he was in the USA, where he spied among the British on behalf of the Americans. After his return, he was quickly promoted to general inspector in the administration of banknotes and coins, thanks not least to his mechanical and chemical skills. He invented a new gravure printing method for bills and devices for striking the coins. His coin press of 1803 earned him the post of general inspector of coins under Napoleon. He later worked in the mint press in Nantes (today's Natural History Museum). In Indre he organized a royal factory for steam engines for ships from 1827. He is buried in Indre.
