希波克拉底（古希腊文：Ἱπποκράτης，前460年－前370年），为古希腊伯里克利时代之医师，约生于公元前460年，后世人普遍认为其为医学史上杰出人物之一。在其所身处之上古时代，医学并不发达，然而却能将医学发展成为专业学科，使之与巫术及哲学分离，并创立了以之为名的医学学派，对古希腊之医学发展贡献良多，故今人多尊称之为「医学之父」。

世人往往将其文集诸位作者的成就、奉行其医学原则的医师及其本人之事迹相混淆，以致于今天，对其真实想法、所书之文、所做之事知之甚微。然而，其仍被认为对临床医学贡献甚多，并总先世医学之大成，堪称古医师之典范。而其所订立之医师誓言，更成为后世医师之道德纲领，直至今天。

Hippocrates of Kos (/hɪˈpɒkrəˌtiːz/; Greek: Ἱπποκράτης; Hippokrátēs; c. 460 – c. 370 BC), also known as Hippocrates II, was a Greek physician of the Age of Pericles (Classical Greece), and is considered one of the most outstanding figures in the history of medicine. He is referred to as the "Father of Western Medicine" in recognition of his lasting contributions to the field as the founder of the Hippocratic School of Medicine. This intellectual school revolutionized medicine in ancient Greece, establishing it as a discipline distinct from other fields with which it had traditionally been associated (theurgy and philosophy), thus establishing medicine as a profession.
