Indian Island (Māori: Mamaku) is an island in Dusky Sound in Fiordland.

[2] Its name stems from first sightings of indigenous people on the island by James Cook in 1773.

[3] The island is situated southeast of Anchor Island and west of Long Island, and is part of Fiordland National Park.

Pest control of introduced animal species such as stoats and rats from 1999 onwards led to the island to be declared pest-free in 2012.
