Nesodden is a municipality in Akershus county, Norway. It is part of the traditional region of Follo. The administrative centre of the municipality is the village of Nesoddtangen. The parish of Næsodden was established as a municipality on 1 January 1838 (see formannskapsdistrikt). The new municipality of Oppegård was separated from Nesodden on 1 July 1915.
The name (Old Norse: Nesoddi) is an old district name. The first element is Nes which means "headland" and the last element is (the finite form of) odde which means "point".The very tip of the peninsula is presently called Nesoddtangen, where the last element is (the finite form of) tange which means "spit". In fact, all three elements in this name have (nearly) the same meaning.
