The Lindsey Islands are a group of islands lying by the north-western tip of the Canisteo Peninsula, in the eastern Amundsen Sea between Ferrero and Cranton Bays, on the Walgreen Coast of Marie Byrd Land, Antarctica.

They form the emergent part of a shelf, less than 200 m deep, made of granitic rocks.

They are mostly ice-free in summer, and two small freshwater ponds are present on the largest island.
