The Amirante Islands are a chain of low coral islands, sand cays and reefs in the Outer Islands of the Seychelles, southwest of the main Mahé island. The group includes several small islands used for limited resort operations, conservation and fishing.

Clear waters, fringing coral reefs and seagrass beds make the archipelago notable for diving, snorkelling and marine biodiversity, and several islands host seabird nesting sites. The islands are sparsely populated or uninhabited and have limited visitor facilities compared with the inner islands of the Seychelles.

Historically the islands have been used intermittently for coconut plantations, guano extraction and limited settlement; more recently a few islands have been developed for low-density tourism and conservation projects. Administration falls under the Outer Islands governance of the Republic of Seychelles.

Geographically the Amirantes lie to the southwest of Mahé in the western Indian Ocean and consist of a linear chain of reefs and islands forming part of the Seychelles outer-archipelago.
