What is the name of the worlds longest river system?
The world's longest river system is the Nile-Kagera River system that flows in eastern Africa. There is some suggestion that the Amazon-Ucayali-Apurimac system in South America may be the largest.
The Murray River of Australia is the longest river in Oceania. Many websites will incorrectly state that the longest river is the Murray-Darling but this is not a river. These are two separate rivers (the Murray and the Darling) which form part of a vast river system known as the Murray-Darling river system.
