Professor Norman Hepburn Baynes (1877–1961) was a noted 20th-century British historian of the Byzantine Empire.
Baynes was Professor of Byzantine History at University College London (UCL) from 1931 until 1942. He was given the title of Emeritus Professor in 1943 and a Doctor of Literature honoris causa in 1951.
In his will he made a bequest to UCL which established 'The Norman Hepburn Baynes Prize' in 1961. The biennial prize is awarded in respect of 'an essay on some aspect of history, including art, religion and thought of the Mediterranean lands within the period from 400BC to 1453AD'.
