longest river

Top-ranking flowing water

The longest river is the river with the greatest length, typically measured from source to mouth.

Which river holds this distinction depends on how tributaries and multiple channels are counted—the Nile and Amazon perpetually compete for the title.

The phrase often appears in trivia contexts: What's the longest river in Africa?
