This study examines Africans contributions to the ecumenical movement from theological and practical perspectives, with particular attention to ecclesiology, Christology, diakonia, interfaith relations, and social transformation within the Churches in Africa. The problem addressed in this work is the persistence of denominational rivalry, cultural tensions, ethnic divisions, and weak ecclesial cooperation in Africa, despite the rapid growth of Christianity on the continent. The study adopts a historical and analytical research method through the examination of relevant books, journal articles, conference reports, and ecumenical documents relating to African Christianity and the global ecumenical movement. Findings reveal that Africa has significantly enriched ecumenism through contextual theology, Ubuntu ecclesiology, missionary cooperation, liberation and reconstruction theology, interfaith dialogue, and collective struggles against colonialism, poverty, and gender injustice. The study further discovers that African spirituality and communal values have strengthened ecumenical consciousness and promoted unity in diversity among churches. However, challenges such as denominational competition, ethnic loyalties, syncretism, and leadership rivalry continue to threaten the future of ecumenism in Africa. The study recommends deeper theological dialogue, intentional ecumenical education, stronger interdenominational collaboration, and renewed commitment to justice, peace, and holistic mission in order to sustain the growth and relevance of ecumenism in Africa and the global Church.
