Nordfjorden is part of Søndeledfjorden in the municipality of Risør in Aust-Agder county, Norway. It lies on the north of the island of Barmen, which is northwest of the city of Risør. Nordfjorden is a little over 7 kilometres (4.3 mi) long. The widest parts are where the Søndeledfjorden goes west and into Søndeled and when the Rødsfjorden joins the Sørfjorden which is on the south side of Barmen island. The south side of the fjord is a relatively straight coastline, but on the north of the fjord there are many coves and bays.
