The Mecklenburg Elbe Valley Nature Park (German: Mecklenburgisches Elbetal) is part of the UNESCO biosphere reserve of Elbe River Landscape.

At over 400 river kilometres long, the Elbe River Landscape Biosphere Reserve runs through the five German states of: Saxony-Anhalt, Brandenburg, Lower Saxony, Mecklenburg-Vorpommern and Schleswig-Holstein.

The nature park was created in 1990 and legally established by act of state in 1998.

Characteristic is the original riparian landscape of the Elbe stream with its tributaries, the Schaale, Sude, Krainke, Rögnitz, Löcknitz and the Müritz-Elde Waterway.

One feature is the areas of inland dunes with sandy calcareous grassland, woods and heaths as well as the steep sides of the Elbe valley near Boizenburg and Rüterberg (Dömitz), whose observation towers offer panoramic view of the Elbe water meadows.
