The Episcopal Conference of the Indian Ocean (French: Conférence Épiscopale de l'Océan Indien, CEDOI) is the episcopal conference of the Catholic Church which includes the following Indian Ocean archipelagic states: Comoros, Mauritius, Réunion, Mayotte and Seychelles.
Since 1974, the bishops of the Indian Ocean islands would gather each year in an informal meeting.
In 1976 the Holy See recognized this assembly with the name of Pastoral Zone of the South West Indian Ocean islands.
In 1985 the assembly obtained from Rome the status of a Bishops' Conference with the official name of Conférence Épiscopale de l'Océan Indien.
Its seat is the town of Port Victoria in Seychelles.
