Ulrich II von Graben (before 1300 – about 1361) was an Austrian noble and member of the Von Graben von Stein family.
He was the son of Ulrich I von Graben and Gertrud (both died ca. 1325). Ulrich II held the titles as burggrave of Hohenwang,Gleichenberg and Rothenfels, Herr of Graben (near Novo Mesto in Carniola) and Wetzelsdorf (near Kornberg in Styria). Together with his brothers Otto and Friedrich I Ulrich II bought in 1328 Herrschaft and Schloss Kornberg. Kornberg will became the family refuge until 1556.
Ulrich II married with Barbara, daughter from Johann von Auersperg and Cimburgis Schauerpeck, and later with a Lady called Gertraud (died before 1375). They had no children.
Von Graben von (zum) Stein, also named, Ab dem Graben, Von (dem) Graben and Vom Graben, is the name of an old Austrian noble family. Originally from Carniola, an apparent (or illegitimate) branch of the House of Meinhardin went on to rule some Carinthian, Tyrolian, East Tyrols, Styrian, Gorizian and modern Italian districts as Burggrafen (a sort of Viscounts) and Lords (Herren) from the early Middle Ages until the 16th-17th century.
Like the Princely Counts of Görz and the Princely Counts of Tyrol the Von Graben descended from the Meinhardins. The earliest known members of the Von Graben family, Konrad and his brother Grimoald von Graben, lived around 1170. Konrad's father may have been a son of Count palatine Engelbert I or his younger brother Count palatine Meinhard I of Gorizia. During the later 13th century the princely family Orsini-Rosenberg descended from a member of the Von Graben family lived at the Grazer Schloss Alt-Grabenhofen, between Reinerkogel and Rosenberg.
