Aenesidemus, fl. 1st century BC. A Greek philosopher who taught in Alexandria and began his philosophical career as a member of the Platonist Academy. He later broke with the Academy to found the "Pyrrhonist" school of classical Skepticism. Aenesidemus' works have not survived. We know of his teachings mostly through the writings of the later Pyrrhonian Sextus Empiricus.
