Toska is an island in Radøy municipality in Hordaland county, Norway. The island lies just west of the island of Radøy in the Hjeltefjorden, at the entrance to the Radfjorden.
A road connection from the village of Manger on Radøy island to the island of Toska was completed in 1989. The island is a popular holiday destination. Toska has about 40 inhabitants, mostly living in the village of Toska, also known as Vestevågen.
There are still a few farmers left on the island, but most residents work in other professions, with many commuting to neighboring villages and even to the city of Bergen.
