Drömling is a sparsely populated depression on the border of Lower Saxony and Saxony-Anhalt in Germany with an area of about 340km2. The larger part belonging to Saxony-Anhalt in the east has been a nature park since 1990. The former swampland was transformed by drainage from a natural into a cultural landscape in the 18th century under the direction of Frederick the Great of Prussia. Today the depression, with its waterways, the Mittelland Canal and the rivers Aller and Ohre is a refuge for rare or endangered species of animal and plant. Most of the area is now made up of nature reserves and protected areas. Nearby towns include Oebisfelde and Wolfsburg.
Drömling lies in a flat hollow measuring about 15 to 20 kilometres across and surrounding by a 60-metre contour. It is a wider section of the Breslau-Magdeburg-Bremen glacial valley. In broad terms it stretches from Wolfsburg-Vorsfelde in the west to Calvörde in the east and from Klötze in the north to Oebisfelde in the south. To the west the geest ridges of the Vorsfelder Werder border on the Drömling.
Drömling extends over the following districts: Salzwedel, Börde, Gifhorn, Wolfsburg and Helmstedt.
