Mittelmark (German, literally "Central March") is a historical region in present-day eastern Germany that was the core territory of the Margraviate of Brandenburg between the Oder and Elbe rivers.
The name refers to the location of the territory between Altmark (Old March) and Neumark (New March) and it lay roughly in the area of the earlier Northern March. The word Mittelmarch is sometimes used, incorrectly, as a replacement for Mittelmark.
The name of Mittelmark was used for a short-lived province of the Kingdom of Prussia in 1713 and again from 1993 to the present[update] for the district of Potsdam-Mittelmark in the German state of Brandenburg.
