The Lübbecke Loessland (German: Lübbecker Lößland) is a natural region that is mainly situated in northeastern North Rhine-Westphalia but with a small area also lying in the western part of Lower Saxony in Germany.
Whilst the southern boundary of the region is clearly defined by the edge of the forests on the Wiehen Hills, its transition to the Rahden-Diepenau Geest is rather more gradual.
Its main characteristic is the rich loess soil that gives the region its name, and which was blown out of the sandur on the edge of the glacier during the last ice age and deposited on the northern slopes of the Wiehen.
Grassland only occurs, if at all, on steep sections of the terrain, e.g. along the course of streams and, in places, immediately next to the forest edges on the Wiehen Hills.
Apart from the short streams that rise in the Wiehen Hills to the south and cut more or less straight across the Lübbecke Loessland without meandering, there are no significant natural waterbodies.
The Lübbecke Loessland begins in the north at about 50 metres above sea level and climbs towards the south, initially gently, but then increasingly steeply.
This corresponds to the western section of today's federal road, the B65, and runs mostly in the more northerly, level part of the Lübbecke Loessland linking the Osnabrück and Minden regions.
