The AFC Challenge League is the third-tier continental club football competition organized by the Asian Football Confederation, designed to develop the game in emerging nations and provide competitive opportunities for clubs from lower-ranked member associations. It serves as an entry point into AFC's club competition pyramid, with participating teams often being domestic cup winners or league runners-up from developing football countries. The tournament format includes group stages and knockout phases, offering valuable international experience. Performance in the AFC Challenge League can lead to promotion to the higher-tier AFC Champions League 2, making it a crucial stepping stone. The competition plays a significant role in spreading football popularity and improving infrastructure and standards in nations where the sport is still growing.
