The Roman Catholic Diocese of Keta–Akatsi (Latin: Ketaën(sis)–Akatsien(sis)) is a suffragan Latin diocese in the ecclesiastical province of Accra in Ghana, yet still depends on the missionary Roman Congregation for the Evangelization of Peoples.
The bishops’ seat is Christ the King Cathedral, in Akatsi. The diocese also contains a co-cathedral: St. Michael’s Cathedral, in the city of Keta.
