Henry I, Count of Berg-Schelklingen (c. 1073 – 24 September 1115) was a Bavarian nobleman who ruled Berg Castle in Ehingen, Bavaria.
The historian Christoph Friedrich von Stälin theorised that their great political power despite humble origins was due to kinship with Bishop St. Otto of Bamberg, who was also Judith's chaplain after her marriage to Władysław I, Duke of Poland, with whom she had a daughter Adelaide, who married Henry's brother-in-law Diepold III, Margrave of Vohburg and gave birth to Adelaide of Vohburg, the first wife of Frederick Barbarossa.
Henry married around 1090 to Adelaide of Mochental, daughter of Diepold II, Margrave of Vohburg and Liutgard of Carinthia.
During the 1090s Henry and Adelaide had three sons and three daughters, who married highly influential nobles from the Houses Přemyslid of Bohemia and Piast of Poland.
Henry and Adelaide had: Diepold II married Gisela of Andechs, daughter of Berthold II, Count of Andechs and Sophia of Istria and they had sons including Bishops Henry, Diepold and Manegold of Passau as well as Berthold, Count of Berg-Schelklingen, who was Rapoto's successor and father of Henry I, the first Margrave of Burgau.
