Big Brother Africa is the African version of the international reality television franchise Big Brother created by producer John de Mol in 1997. The show was first aired in 2003 for one season on M-Net and broadcast to audiences in 42 African countries. In 2007, the show was back from four-year hiatus, until it got cancelled after season nine in 2014.

The African version initially involved 12 countries within Africa (Angola, Botswana, Ghana, Kenya, Malawi, Namibia, Nigeria, South Africa, Tanzania, Uganda, Zambia & Zimbabwe) with two countries (Ethiopia and Mozambique) being added in season 4 and two other countries (Liberia and Sierra Leone) being added in season 7 while Rwanda was added in season 9. Each country provides at least one contestant living in an isolated house while trying to avoid being evicted by viewers and ultimately winning a large cash prize at the end of the show. The show is co-produced by Endemol South Africa.

A special edition of the Big Brother Africa franchise called Big Brother Titans was announced and will premiere on 15 January 2023. It faces off brand-new contestants from South Africa and Nigeria.
