The Muni (French: Rivière Muni, Spanish: RÃÂo Muni) is an estuary of several rivers of Equatorial Guinea and Gabon. Part of its length forms part of the border with Gabon. It is from this estuary that the former name for this part of Equatorial Guinea, RÃÂo Muni was taken.
The estuary is fed in the north by the Congue and the Mandyani rivers and from the east by the Mitong, the Mven and the Timboni rivers (Mitimele, Utamboni).
