João Pereira (born 10 July 1977 in Benguela), is a retired Angolan footballer. He last played for Atlético Sport Aviação.
Jamba is an archetype of old fashioned defending. He is known for playing reliably and consistently.
The central back is a former member of the national team, and was called up to the 2006 World Cup. He has played in 29 straight international competitions for Angola, making him a leader on an otherwise young club. In April 2006, his performances were acknowledged when he was voted Angola's best home-based player in a national radio poll.
His nickname, "Jamba," means "Elephant" in Umbundu, a language spoken in southern Angola.
