The U-20 Africa Cup of Nations, known for short as the U-20 AFCON and for sponsorship purposes as TotalEnergies U-20 Africa Cup of Nations, previously known as the African Youth Championship and the African U-20 Championship, is the biennial international youth football tournament organized by the Confederation of African Football (CAF) for its nations consisting of players under the age of 20.

It serves as the African qualification tournament for the FIFA U-20 World Cup.

In 1979, FIFA created a world championship for upcoming footballers, causing CAF to install a home-and-away qualification tournament for African nations called the African Youth Championship which also crowned the tournament's champions.

On 6 August 2015, the CAF Executive Committee decided to change the tournament's name to the Africa U-20 Cup of Nations in line with the flagship Africa Cup of Nations tournament.

On 21 July 2016, French energy and petroleum giant TotalEnergies (formerly Total S.A.) secured an 8-year sponsorship package from CAF to support its competitions.
