Pedanius Dioscorides (Ancient Greek: Πεδάνιος Διοσκουρίδης, Pedianos Dioskorides; c. 40 – 90 AD) was a Greek physician, pharmacologist, botanist, and author of De Materia Medica (Ancient Greek: Περὶ ὕλης ἰατρικῆς) —a 5-volume Greek encyclopedia about herbal medicine and related medicinal substances (a pharmacopeia), that was widely read for more than 1,500 years. He was employed as a medic in the Roman army.

A native of Anazarbus, Cilicia, Asia Minor, Dioscorides practised medicine in Rome during the reign of the emperor Nero. He was a surgeon with the Roman army, which gave him the opportunity to travel extensively, at the same time seeking medicinal substances (plants and minerals) from all over the Roman Empire. The name Pedanius is Roman, suggesting that an aristocrat of that name sponsored him to become a Roman citizen. He dedicated his medical books to Laecanius Arius, a medical practitioner of Tarsus in Cilicia, so he may have studied medicine there.

Between AD 50 and 70 Dioscorides wrote a five-volume book in his native Greek, Περὶ ὕλης ἰατρικῆς, known more widely by its Latin title De Materia Medica ("On Medical Material") which became the precursor to all modern pharmacopeias.

In contrast to many classical authors, Dioscorides' works were not "rediscovered" in the Renaissance, because his book had never left circulation; indeed, with regard to Western materia medica through the early modern period, Dioscorides' text eclipsed the Hippocratic corpus. In the medieval period, De Materia Medica was circulated in Greek, as well as Latin and Arabic translation. While being reproduced in manuscript form through the centuries, it was often supplemented with commentary and minor additions from Arabic and Indian sources. A number of illustrated manuscripts of De Materia Medica survive. The most famous of these is the lavishly illustrated Vienna Dioscurides, produced in Constantinople in 512/513 AD. Densely illustrated Arabic copies survive from the 12th and 13th centuries, while Greek manuscripts survive today in the monasteries of Mount Athos.
