Lupo II[1] (died 778) is the third-attested historical Duke of Gascony (dux Vasconum or princeps[2]), appearing in history for the first time in 769.
[3] In 769, a final rising of the Aquitanians against Charlemagne and Carloman was put down, and the rebel Hunald II was forced to flee to the court of Lupo in Gascony.
[4] Lupo, however, did not desire to bring down upon himself the wrath of the Frankish kings and handed Hunald, along with his wife, over to Charlemagne.
If he is to be regarded as related to subsequent Gascon dukes, which seems reasonable on the basis of patronymics, a genealogy can easily be constructed.
All of his sons ruled Gascony at one time or another, except García, who died in battle with Berengar of Toulouse in 819.
