The Gudenus family is a prominent German noble family, originating in Hesse, whose noble ancestry can be traced back to the 16th century.

Since 1774, the family ruled the Lordship of Umpfenbach, which they had acquired from the Castell-Remlingen branch of the Castell family. Holding Imperial Immediacy, the estate was eventually sold in 1805 to the House of Trauttmansdorff. Throughout centuries, the Gudenus family was divided into two lines, one comital and one baronial. The first line, which held the title of Count, granted to 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 to them on 15 April 1756, settled in the Duchy of Styria and Kingdom of Hungary.
