Harenberg is a district of the town Seelze, in the district of Hanover, in Lower Saxony, Germany.
Harenberg is situated approximately 2 km west of the city of Hanover, close to the Bundesstrasse 441. The village lies on a flat landscape behind a hill, from which point there is a far-reaching view around, to Seelze and Hanover, as well as toward the Deister. Harenberg also includes three smaller settlements outside the village. These are the settlements Kollrothshöh (on the hill halfway between Hanover and Harenberg), Cemetery (on the street linking Harenberg and Seelze) and Mill (on the Linnenberg hill between Harenberg and fellow village Döteberg), which lie on the historical access roads to Harenberg.
Harenberg can perhaps be traced back to the late Saxon settlement period of the 8th century. Its existence can more conclusively be validated from 1220 onward (documents from Hildesheim dated back to 1195 also may refer to it, but the obscurity of the spelling means this is not definitive). There is believed to have been an aristocratic family in Harenberg, who called themselves after their residence 'von Harenberg'. A Bernhard von Horenberge is mentioned in a Westphalian documents book from this time.
