Map - Songdalen

Songdalen is a former municipality in the old Vest-Agder county, Norway. The municipality existed from 1964 until 2020 when it was merged with Søgne and Kristiansand municipalities to form a new, much larger Kristiansand municipality in what is now Agder county. It was located in the traditional district of Sørlandet, just outside of the city of Kristiansand. The administrative centre of the municipality was the village of Nodeland. Other villages in the municipality included Brennåsen, Finsland, Kilen, Nodelandsheia, and Volleberg. The Sørlandsbanen railway line ran through the municipality, stopping at Nodeland Station. The European route E39 highway also ran through the southern part of the municipality.

Prior to its dissolution in 2020, the 216 km2 municipality is the 323rd largest by area out of the 422 municipalities in Norway. Songdalen is the 161st most populous municipality in Norway with a population of 6,568. The municipality's population density is 31.8 PD/km2 and its population has increased by 16% over the last decade.

Songdalen was a relatively new municipality. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the municipality of Greipstad (population: 2,061), most of the municipality of Finsland (population: 797) except for the Kleveland bru area, and the Eikeland area of Øvrebø (population: 39) were all merged to form the new municipality of Songdalen. On 1 January 1978, a small area of Vennesla municipality (population: 10) was transferred to Songdalen. Then on 1 January 1984, the unpopulated Hauglandsvatnet area was transferred from Vennesla to Songdalen.

On 1 January 2020, the three neighboring municipalities of Kristiansand, Songdalen, and Søgne merged to form one large municipality called Kristiansand.
