Nannestad is a municipality in Akershus county, Norway. It is part of the traditional region of Romerike. The administrative centre of the municipality is the village of Teigebyen.
Nannestad was established as a municipality on 1 January 1838 (see formannskapsdistrikt).
Store norske leksikon writes that "At søndre LÃÂ¥ke gÃÂ¥rd (a farm), South of Nannestad Church, Skule BÃÂ¥rdsson beat Birkebeinar (a political group), [... on a battlefield] South of the farm".
The municipality (originally the parish) is named after the old Nannestad farm (Old Norse: Nannastaðir), since the first church was built here. The first element is the genitive case of Nanni (an old Norse male name) and the last element is staðir which means "homestead" or "farm".
The coat-of-arms is from modern times. They were granted in 1990. The arms show three yellow coltsfoot flowers on a green background. This is a flower that is prevalent in the area.
Nannestad is located in northwestern Akershus county, with inhabitants concentrated at Romerikssletta. It includes the villages of Maura, ÃÂ sgreina, EltonÃÂ¥sen, SteinsgÃÂ¥rd and Teigebyen, that last being the administrative centre.
