15 Longest Rivers in the World

15 Longest Rivers in the World

Want to know which is the world’s longest river? Here’s a list of the 15 longest rivers in the world by their total length. 

Measuring the total length of a river can be somewhat challenging since there isn’t always a clear start and finish since many rivers are connected to larger and smaller tributaries.

Therefore, there is an ongoing debate on whether the Nile or the Amazon River is the longest river in the world. New findings have led most experts to agree that the Nile is slightly longer than the Amazon River, making it the world’s longest river. 

Amur River

The Amur River (Chinese: Heilong Jiang) forms the natural border of far East Russia and China with a total length of 4444 kilometers, making it the 10th longest river in the world. 

It has two tributaries, Argun and Kherlen and flows in a northeastern direction until it empties in the Pacific Ocean.
