Hügelland is a type of landscape consisting of low rolling hills whose topography or surface structure lies between that of a lowland region (plains or river terraces) and that of a more rugged hill range or low mountain range. The term is German and has no exact equivalent in English, but is often translated as "hill country", "hilly terrain", "upland(s)" or "gently undulating" or "rolling country", or "rolling countryside". It is derived from Hügel, a low hill or hillock and appears frequently as a proper name for this type of terrain.
