Charmaina (Greek: Χάρμαινα) was a medieval settlement and Eastern Orthodox bishopric.
Its exact location is unknown, but Charmaina lay on the western slopes of Mount Ossa, near modern Marmarini , Greece. The name is of Slavic origin, and first attested in the 11th century, when it was a bishopric.[1] It is attested as an active see through the Notitiae Episcopatuum of the Patriarchate of Constantinople until the 15th century.[1]
The settlement featured a monastery dedicated to the Panagia, which in 1277 became property of the Makrinitissa Monastery.[1]
