Sørøya (Northern Sami:Sállan) is a Norway's eight largest island in terms of area, and is divided between the municipalities of Hasvik and Hammerfest. It is often claimed to be 'one of the most beautiful' of the islands in Norway.

The island is surrounded by the Norwegian Sea on the north and the Sørøysundet to the south. Across the Sørøysundet are three large islands: Stjernøya, Seiland and Kvaløya. The island of Sørøya has no bridge or tunnel access, only a regular ferry route from Hasvik to Øksfjord on the mainland. Hasvik Airport is located on the southern tip of the island.
