Edgeøya, occasionally anglicised as Edge Island, is a Norwegian island located in southeast of the Svalbard archipelago; it is the third largest island in this archipelago. An Arctic island, it forms part of the Søraust-Svalbard Nature Reserve, home to polar bears and reindeer. Its eastern side is covered by an ice field. The island is 5,073 square kilometres (1,960 sq mi) in area, making it the third largest in the Svalbard archipelago. The island is named after Thomas Edge (died 1624), an English merchant and whaler. It is seldom visited today.
