The Akrofi-Christaller Institute of Theology, Mission and Culture (ACI), formerly known as the Akrofi-Christaller Memorial Centre for Mission Research and Applied Theology, is a tertiary, postgraduate research and training institute located in Akropong-Akuapem in Ghana.

[1][2] The institute was set up to study and document Christian religious thought, history and theology through the lens of culture, historiography and life in Ghanaian society and Africa as well as scholarship on ecumenical relations between the continent and the rest of the world.

[1][2] The university was named after two Christian ethnologists, Johann Gottlieb Christaller and Clement Anderson Akrofi who carried out extensive literary work on the Twi language.

[3][4] With roots in the Pietistic tradition of the Basel Mission, the Institute combines academic study with propagation of the Gospel in Ghana and Africa.

[1][2] Akrofi-Christaller Institute occupies the buildings of the historic Akropong Seminary including the Basel House in Akropong-Akuapem, a campus that was built in the mid-nineteenth century, renovated in the early nineties and expanded by the turn of the millennium.
