Rygnestadtunet is a farmyard museum at Nordigard, Nørdre Rygnestad in the municipality of Valle in the Setesdal region of Aust-Agder, Norway. It is located near the junction between highways 9 and 45. The farm museum today looks exactly as it did when it was deserted in 1919 and preserved in 1923. It was opened as a museum in 1940. Excavations in the area indicate that the site has been populated since at least 900 AD.
