Barentsøya, sometimes anglicized as Barents Island, is an island in the Svalbard archipelago, Norway, lying between Edgeøya (Edgeøya) and Spitsbergen. Barents Island has no permanent human inhabitants. Named for the Dutch explorer Willem Barents (who actually never sighted the island), it is a part of Søraust-Svalbard Nature Reserve.
An Arctic island, around 43 per cent of its area of is glaciated. To the north, in the sound between Barentsøya and Spitsbergen, lies the island of Kükenthaløya. To the south, the sound separating Barents Island from Edgeøya is Freemansundet.
