African Petroleum Producers Organization (APPO) (Organisation Africaine des Producteurs Pétroliers in French, Organização dos Produtores Africanos de Petróleo in Portuguese and المنظمة الأفريقية لمنتجي البترول in Arabic) is an organization of African countries producing petroleum. It was created on January 27, 1987, in Lagos, Nigeria, to serve as a platform for cooperation and harmonization of efforts, collaboration, sharing of knowledge and skills among African oil producing countries. The headquarters of the organization is in Brazzaville in the Congo. The Organization changed its name from African Petroleum Producers Association to African Petroleum Producers Organization in 2017.

The founding of APPO was spearheaded by Nigeria as an effort to mitigate the nation's dependency on Western technology and Western markets for oil export revenues. The objective of APPO is to promote cooperation in petrochemical research and technology.
