Louis Robert (Laurière, 15 February 1904 - Paris, 31 May 1985) was a professor of Greek history and Epigraphy at the Collège de France, and author of many volumes and articles on Greek epigraphy (of all periods, from the archaic period to Late Antiquity), numismatics, and the historical geography of Greek lands.
He was made full professor at the Collège de France in 1939, where he remained until his retirement in 1974.
He continued to publish on Greek epigraphy with his wife, Jeanne Robert, as co-author, as he had done since their marriage and until his death in 1985.
