Oliver Mathison (1914 – unknown) was a German farmer and member of the German Brotherhood of Assassins operating in Germany during World War 2. Having grown up on a farm, Oliver remained unaware of his assassin heritage until the age of twenty-five, when his father was murdered by the Nazi's during the Gleiwitz Incident. Fleeing the countryside in fear of his life, he was eventually found and taken in by the German Master Assassin, James von Moltke.
