Edmund Groag (2 February 1873, in Prerau – 19 August 1945, in Vienna) was an Austrian classical scholar, who specialized in Roman history.
By way of a study grant he visited Rome in 1898/99, then in 1901 began work at the Vienna National Library, an institution that he would be associated with for most of his career.
In 1918 he obtained his habilitation at the university, where in 1925 he was named an associate professor of Roman history.
During the Nazi takeover of Austria, he lived in a precarious state in Vienna.
