The Dümmer Geest Lowland (German: Dümmer-Geestniederung) is a natural region unit of the 3rd level in northwest Germany that mainly extends over southwestern Lower Saxony with a small area over the border in North Rhine-Westphalia. Its uniqueness consists in the very varied juxtaposition of different landscape elements of the Northern Lowlands of which the Dümmer Geest Lowland is a part.
