The North European Plain (German: Norddeutsches Tiefland or German: Norddeutsche Tiefebene), or Middle European Plain (Polish: Nizina Środkowoeuropejska) is a geomorphological region in Europe, mostly in Poland, Denmark, Germany, Belgium, the Netherlands (Low Countries), and a small part of northern France.
It consists of the low plains between the Hercynian Europe (Central European Highlands) to the south and coastlines of the North Sea and the Baltic Sea to the north. These two seas are separated by the Jutland Peninsula (Denmark). The North European Plain is connected to East European Plain, together forming the European Plain.
The Northern European Plain's main use is commercial farming, with little natural vegetation remaining.
Elevations vary between 0 and 200 m (about 0 to 650 ft). While mostly used as farmland, the region also contains bogs, heath and lakes. On the North Sea coast one finds the Wadden Sea, a large tidal area.
On the Baltic Sea coast one finds the Szczecin Lagoon, the Vistula Lagoon and the Curonian Lagoon, a number of large freshwater lagoons.
