The Chagos Conservation Trust is a charitable association, established in 1992 (as Friends of the Chagos), whose aims are to promote conservation, scientific and historical research, and to advance education concerning the Chagos Archipelago in the British Indian Ocean Territory.

Its vision is to ensure that the globally important natural environment of the Chagos is well protected, conserved and understood, inspiring the better management and protection of our planet.

CCT works to advance international understanding of the global environmental importance of the Chagos, to ensure its protection for the wider public benefit.

It has led many expeditions to the territory and, through these, has amassed a considerable amount of scientific data. In 2017, it launched the Chagos Information Portal (ChIP) to bring together this information in a meta-catalogue.
