Tveitetunet is an open-air museum located at the Nordigard Tveiten (Tveiti) farm in the municipality of Valle in Agder county, Norway. The museum lies about 3 kilometres (1.9 mi) south of the village of Valle, just about 1.2 kilometres (0.75 mi) up the hill to the east of the Norwegian National Road 9, just east of the river Otra. The museum was opened in 1977, and it consists of a courtyard and several surrounding farm buildings on a 10-decare (2.5-acre) piece of farmland.
