The Subantarctic Indian Ocean bioregion consists of four island groupings in the South Indian Ocean, about halfway between the Cape of Good Hope in South Africa and the Antarctic mainland. The islands are unified by one tundra ecoregion—Southern Indian Ocean Islands Tundra (133)— and surrounding marine areas.

The Subantarctic Indian Ocean Islands bioregion is part of the Antarctic Continent & Islands subrealm and is made up of one ecoregion: Southern Indian Ocean Islands Tundra [1].
