The March of the Nordgau or the Bavarian Nordgau was a margraviate in the north of the duchy of Bavaria in the High Middle Ages. It covered the region roughly covered by the modern Upper Palatinate along the river Main. The chief cities of the Nordgau were the Frankish cities Nuremberg and Bamberg and, especially after 1061, Eger in the Egerland part of the Nordgau.
