Barbara M. Levick (born 21 June 1931) is a British historian and epigrapher, focusing particularly on the early Roman Republic and late Empire. She is recognised within her field as one of the leading Roman historians of her generation.
Levick was educated at St Hugh's College, Oxford. Her DPhil, on the subject of Roman colonies in South Asia minor was undertaken in the mid 1950s and supervised by Ronald Syme. For this research she made two solo trips to Turkey, placing herself in a tradition at this time of largely Scottish and male epigraphers travelling in Anatolia. She focused however on Psidia, a region that lay away from the routes explored by a group of her male contemporaries, although she was the only one to publish a book as a result of research from these expeditions.
In 1959 Levick was appointed a university Fellow and tutor for Roman History at St Hilda's College, Oxford, and in 1967 published her first monograph, drawing on material from her doctoral thesis, which forty years after its publication was described as a "resilient classic of Roman history".  The importance of this work came from both its focus on the Roman impact on Asia Minor, and the drawing together of both epigraphic and numismatic evidence. In this work she used the discoveries she made at Yalvaç, and considered again material that had been neglected since the 1920s.
She was an influential editor of inscriptions who shaped the format of the Monumenta Asiae Minoris Antiqua series, directing two volumes of its publication. Her biographies of Roman emperors and Imperial women are widely known and receive largely positive reviews from their critics.
