Sandøya (Sand island) is an island along the southern coast of Norway. It has roughly 230 permanent residents (2001), and shares its local administration with the surrounding communities and the nearby town Tvedestrand. The island has no bridge to the mainland, and the inhabitants rely on boats for transportation. Cars are parked at the nearby island Borøya. There are only four cars on the island, which are seldom in use. Being close to the popular tourist attraction Lyngør (a nearby group of islands frequented by thousands of tourists every summer), Sandøya is a popular summer vacation spot.
