Heinrich Karl Wilhelm Berghaus (3 May 1797 – 17 February 1884) was a German geographer and cartographer who conducted trigonometric surveys in Prussia and taught geodesy at the Bauakademie in Berlin. He taught cartography and produced a pioneering and influential thematic atlas which provided maps of flora, fauna, climate, geology, diseases and a range of other information. He was a friend of Alexander von Humboldt and produced some of the maps used in his publications. A nephew Hermann Berghaus also worked in cartography.
