Sjonbotn is a village in Rana Municipality in Nordland county, Norway. It is located along Norwegian County Road 17 at the eastern end of the Sjona fjord, about 2 km north of the villages of Utskarpen and Myklebustad. The small, rural village area sits at the end of the fjord. There is a large marshy river delta at the shoreline that is known as Mæla, a name that is also used for the village area as well. The district surrounding the inner part of the Sjona fjord originally belonged to Nesna Municipality. On 1 January 1964, this district (population: 543) was merged with the town of Mo i Rana, Nord-Rana Municipality, and the northern part of Sør-Rana Municipality to create the new Rana Municipality.
