The region's name is based on the Latin name Alba for the Elbe River and refers to an area predominantly located north of the Lower Elbe, roughly corresponding with the present-day Holstein region. Situated in what is now Northern Germany, this is the earliest known dominion of the Saxons.

==Geography== According to the 1076 Gesta Hammaburgensis ecclesiae pontificum by chronicler Adam of Bremen, Nordalbingia consisted of three tribal areas (Gaue): Dithmarschen, stretching along the coast of the North Sea from the mouth of the Elbe River to the Eider River in the north Holstein proper, situated on the Stör River, a right tributary of the Elbe Stormarn on the north bank of the Elbe, including the present-day area of Hamburg. The Nordalbingian tribes were allied with the Saxons settling in Land Hadeln (Haduloha) south of the Elbe. In the east, the Limes Saxoniae, an inaccessible region between the Elbe and today's Kiel Fjord on the Baltic Sea, formed a natural border with the Wagria lands settled by Slavic Obotrites.
