The Gauliga Nordmark was the highest football league in the Prussian Province of Schleswig-Holstein and the German states of Hamburg, Lübeck, Mecklenburg-Schwerin, Mecklenburg-Strelitz and parts of Oldenburg from 1933 to 1945.

The German word Nordmark can be translated as Northern Marches, referring to the fact that the league covered the northernmost part of the country.

The league retained its modus until 1937, when two clubs, the Borussia Harburg and FV Wilhelmsburg 09 transferred across from the Gauliga Niedersachsen.

Unlike all other leagues in the country, the Gauliga Hamburg managed to complete its program in its last season, 1944–45 before the collapse of Nazi Germany finished all competition.

Of the clubs from the region Nordmark, only the Luftwaffen-SV Hamburg achieved any form of national success during the Gauliga years.

With the end of the Nazi era, the Gauligas ceased to exist and the northern part of Germany found itself in the British occupation zone.

In the British zone, top-level football did not resume straight away, unlike in Southern Germany, and only in 1947 was a new, highest league introduced, the Oberliga Nord, which covered the new states of Lower Saxony and Schleswig-Holstein along with the recreated city-states of Hamburg and Bremen.
