Dypvåg is a former municipality in the old Aust-Agder county, Norway. The 15-square-kilometre (5.8 sq mi) municipality existed from 1838 until its dissolution in 1960 when it was merged into the present-day municipality of Tvedestrand which is in Agder county. The small municipality included the coastal area about 8 kilometres (5.0 mi) east of the town of Tvedestrand and several islands located just offshore. The administrative centre was the village of Dypvåg where the Dypvåg Church is located.
