Nes 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 Årnes.The municipality (originally the parish) is named after the old Nes farm (Old Norse: Nes which means "headland"), since the first church was built here. The actual nes is the headland made by the two great rivers Glomma and Vorma, which have their meeting point just south of the farm. Prior to 1889, the name was spelled "Næs".
The coat-of-arms is from modern times. They were granted in 1988. The arms show three yellow logs (to represent forestry) on a green background (to symbolize youth and hope). The position of the logs represents the meeting of the rivers Glomma and Vorma, creating the headland of Nes.The parish of Næs was established as a municipality of its own on 1 January 1838 (see formannskapsdistrikt).
