Zosimos of Panopolis () was an Egyptian-born Greek alchemist and Gnostic mystic who lived at the end of the 3rd and beginning of the 4th century AD. He was born in Panopolis (present day Akhmim, in the south of Roman Egypt), and flourished ca. 300. He wrote the oldest known books on alchemy, which he called "Cheirokmeta," using the Greek word for "things made by hand." Pieces of this work survive in the original Greek language and in translations into Syriac or Arabic. He is one of about 40 authors represented in a compendium of alchemical writings that was probably put together in Constantinople in the 7th or 8th century AD, copies of which exist in manuscripts in Venice and Paris. Stephen of Alexandria is another.
