The Ebenezer Presbyterian Church, formerly known as the Basel Mission Church, Christiansborg, is a historic Protestant church located in the suburb of Osu in Accra, Ghana. The church was founded by the Basel Evangelical Missionary Society in 1847. Previously near the Christiansborg Castle at a hamlet called Osu Amanfong, where a commemorative monument now stands, the church relocated northwards to its present location near the Salem School when a new chapel was constructed and consecrated in 1902. The church is affiliated to the Presbyterian Church of Ghana. Liturgical services are conducted in English and the Ga language.
