Scott Island is a small uninhabited island of volcanic origin in the Ross Sea, Southern Ocean, 505 kilometres (310 mi) northeast of Cape Adare, the northeastern extremity of Victoria Land, Antarctica.

The island was discovered and landed upon on 25 December 1902 by captain William Colbeck, commander of the SY Morning, the relief ship for Robert Scott's expedition.

In 2006, a mapping expedition to the Ross Sea found the islands 2.3 kilometres (1.4 mi) north of their previously determined position.
