The Aldabra Group are part of the Outer Islands of the Seychelles, lying in the southwest of the island nation, around 1,100 kilometres (680 miles) from the capital, Victoria, on Mahé Island.

The group contains four islands and atolls. By far the largest in terms of area is Aldabra Atoll, with a total land surface area of 155km, consisting of four main islands (Grand Terre, Malabar, Picard, and Polymnie) and many smaller islets. Aldabra Research Station (on Picard) was established by the Royal Society in 1971 and is Aldabra's only permanent settlement, with a small group of scientists, conservationists, and support staff. There is a small settlement on Assumption, as well as an airstrip. There are small lodges on Astove and Wizard Island, Cosmoledo Atoll. The total land area of the Aldabra Group is 180.03 km.
