Monasao, also spelled Monassao, is a village situated in Sangha-Mbaéré Prefecture, Central African Republic.

A French missionary, Renè Ripoche, established Monassao in 1975 to settle Baka people.

Currently, Monasao is not solely settled by Pygmy, but also by Bantus.

A Catholic mission is present in Monasao, and it covers four villages.
