The term 'RICH' is a very relative term. To answer your question, I would give you the top five richest African countries (based on their economic standing), since a lot of African countries are infact ''RICH'' but due to some factors, have not been able to maximize their economic potential! Also, various lists have varied. They are in no particular order: 1. Algeria 2. Nigeria, 3. Egypt, 4. Libya, 5. South Africa.
