Årnset[3] or Rissa[4] is the administrative centre of Indre Fosen Municipality in Trøndelag county, Norway.

It is located on the north shore of the lake Botn about 10 kilometres (6.2 mi) south of the village of Hasselvika and about 12 kilometres (7.5 mi) north of the villages of Stadsbygd and Askjem.

[1] Rissa Church, Rein Church, and Rein Abbey are all located in and around Årnset.

Prior to 2020, the village was the administrative centre of the old Rissa Municipality (which is why the village is known as Rissa).
