Tjøtta is an island in the municipality of Alstahaug in Nordland county, Norway. The 11.3-square-kilometre (4.4 sq mi) island lies at the entrance to the Vefsnfjorden, just south of the island of Alsta. The U-shaped island is relatively flat, and the highest point is the 77-metre (253 ft) tall Kalvberghaugen, just east of the village of Tjøtta. The island has two main villages on it: Tjøtta and Svinnes. The Norwegian County Road 17 crosses the island and it connects it to Alsta by two causeways.
Tjøtta has one of the largest and oldest Iron Age farms in Northern Norway, and hardly any places in the region have this many historical relics preserved in one limited area. The chief Hårek av Tjøtta was from here. He was known in the stories of Snorre Sturlason as the governor of Hålogaland.
Gullhaugen is located on Tjøtta. The name comes from the Old Norse word haugr meaning hill or mound. Gullhaugen is the site of a large burial mound consisting of over 30 mounds, 5 large round mounds, several elongated mounds, 2 large burial cairns, several stone rings, and a large number of smaller round mounds. The largest mound is about 25 metres (82 ft) across and about 2 to 3 metres (6 ft 7 in to 9 ft 10 in) high. All the mounds in this part of the cemetery has been dated back to the Iron Age.
