Friedrich Cornelius (2 July 1893 – 8 January 1976) was a German historian who specialized in ancient history.
He joined the Nazi Party in July 1930 and subsequently became Ortsgruppenleiter and Mayor of Garching bei München.
He completed his habilitation on Roman history at the University of Würzburg in 1939 under the supervision of Alexander Schenk Graf von Stauffenberg.
During this time, Cornelius wrote a work on Erich Ludendorff and, with Walter Eckhardt, a multi-volume series on the early history of the Germanic peoples.
Cornelius was well-known for having used cuneiform tablets to correctly estimate the years in which Hammurabi reigned.
