The Indian Ocean Commission (French: Commission de l'Océan Indien, COI) is an intergovernmental organisation that links five African Indian Ocean nations — i.e. Comoros, Madagascar, Mauritius, Réunion (France), and Seychelles. There are also eight observers as of August 2025 — i.e. China, the European Union, La Francophonie, the Order of Malta, India, Japan, the United Nations and South Korea.
The IOC was created in 1982 in Port-Louis, Mauritius, and institutionalised in 1984 by the Victoria Agreement (Seychelles). The organisation coordinates cooperative efforts amongst its member and observer nations which primarily focus on environmental management and preservation. Some of the more specific areas of focus in its past projects include maritime concerns and fisheries, the needs of growing island states, adapting to climate change outcomes, food security and public health.
