Seiland (Northern Sami:Sievju) is the eighth largest island in mainland Norway, located in Finnmark county. The 559-square-kilometre (216 sq mi) island is divided between the municipalities of Alta, Hammerfest, and Kvalsund.

Archeological excavations have shown that people have lived on Seiland for over 7000 years. Today, however the only people on it live in a few relatively isolated areas such as from Altneset to Hakkstabben on the southern tip of the island; Kårhamn on the northwestern side; and the Hønseby, Eidvågen, Fiskebukta, Survika areas in the northern part of the island. In 2006, the majority of central Seiland was designated as Seiland National Park.
