Diepold III, Margrave of Vohburg
Diepold III, Margrave of Vohburg, also known as Diepold von Vohburg and Diepold III von Giengen, was a Bavarian noble in the 12th century. He had two wives. His daughter with Adelaide of Poland, Adelheid of Vohburg, was the first wife of Frederick I, Holy Roman Emperor. Their son Diepold IV died in 1130.
His second wife was Kunigunde von Beichlingen. Their daughter Kunigunde von Vohburg married Ottokar III of Styria.
The title had originally referred to the families' holdings along the border with Bohemia, but after Diepold's death the title was transferred to the Bavarian lands proper of the family.
In 1133 Diepold III founded a Cistercian abbey at Waldsassen.
