The parish of Soggendal was established as a municipality January 1, 1838 (see formannskapsdistrikt). The small lading place of Sogndalstrand was separated from Sokndal as a municipality of its own in 1858, but again merged with Sokndal in 1944.
Sogndalstrand is a picturesque, old fishing village, which may have inspired the municipality in becoming Norway's first member of Cittaslow.
At Tellnes near Hauge i Dalane, there is an ilmenite mine run by Titania AS, supplying 10% of the world production of ilmenite. It's also the world's largest opencast ilmenite mine.
The fjord Jøssingfjord, known for the Altmark Incident, is also located in Sokndal.
The lake Eiavatnet borders on the municipality.
Until 1918 the name was written "Sogndal".
