The 2005 ICC Africa/East Asia-Pacific Under-19 Championship was a cricket tournament held in South Africa from 21–26 August 2005, during the 2005 international season. All matches were held at the Willowmoore Park complex in Benoni, Gauteng.
Namibia won the tournament by defeating Uganda in the final, with both teams qualifying for the 2006 Under-19 World Cup in Sri Lanka. Tanzanian batsman Benson Mwita led the competition in runs scored, while Kenya's Rohit Vekaria took the most wickets. Ugandan all-rounder Ronald Ssemanda was Player of the Final.
The tournament was jointly organised by the African Cricket Association (ACA) and ICC East Asia-Pacific (EAP), with eight teams (six African and two EAP) participating, divided into two pools for the group stages. Another joint tournament had been held in 2003, for the 2004 World Cup, but separate qualifying tournaments have been held since – the ICC Africa Under-19 Championships and the EAP Under-19 Cricket Trophy.
