Groß Ellershausen is a village (borough: Ortsteil) in Göttingen, Germany. The village lies on highway B3, west of the southern part of the city proper, separated from it and the River Leine by the Autobahn A7. Further west, just beyond the village is the 77 hectare local forest, Genossenschaftsforst Groß Ellershausen. From the village, running north and then through the forest is a bicycle- cum foot-path built on the old Hannöversche Südbahn railway line.
The earliest written record of the village is from the year 989 in the Traditiones Corbeyenses of the Corvey Abbey (III § B 115b), where it is called "Aliershusun". The village church was built in the 11th century, and is one of the oldest structures in southern Lower Saxony. In 1144, the village was presented to the Bursfelde Abbey (Ib.). In a record from 1574, the earliest record of the name "Ellershausen" can be found.
During the Thirty Years War, the village suffered the depredations of war and pillage common to the era and area. Once again, in the Seven Years' War, the village was brutally used by Freikorps Fischer.
The village has suffered more than once the ravages of flood-waters. The earliest know such disastrous flooding was on 29 April 1800, with damaging high water also coming in August 2007. 
Through the 19th century the village was an agricultural community that also profited from the orderly exploitation of the village woodland. A few craftsmen also plied their trades. In 1856, the (Ib.) Hannöversche Südbahn was completed, with the line passing through the community. However, it was not until 1931 that trains stopped at the village. In 1980, the line was discontinued. (Ib.) By this time, bus service and possession of personal automobiles were commonplace and extensive, and a significant proportion of the villagers were commuters to work or school in nearby Göttingen.
There are over fifty businesses in the village.
There is a volunteer fire department. (http://www.kfv-goe.de/index.html)
Mayor: Heidrun von der Heide
The population of the village stood at 1,421 in 2006.
The community is, like the region in general, predominantly Lutheran. There is one church in the village, St. Martini, built in the 10th or 11th century and said to be one of the oldest surviving structures in southern Lower Saxony. Administratively, the church is part of the Sprengel Hildesheim-Göttingen der Evangelisch-lutherischen Landeskirche Hannovers.
Since at least the early 19th century, there have been a number of social facilities and societies and clubs in Groß Ellershausen.
