The Gudenus family is a prominent German noble family, originating in Hesse, Germany, whose ancestry can be traced back to the 16th century.
Throughout centuries, the Gudenus family was divided into two lines. The first line, which held the title of Count, granted them on 22 October 1907 by Franz Joseph I, settled in Austria, while the other line of the family, which held the title of Baron, granted them on 15 April 1756, settled in the Duchy of Styria and Kingdom of Hungary.
