Largest Rivers of the World

 

An authoritative list of the world’s largest rivers has

never been printed anywhere. Many of the largest

rivers in the world are in the tropics (Brazil, Colombia,

Congo, Indonesia, New Guinea, etc.) and some have never

been accurately measured.  The world's largest megarivers

are probably all listed below, but the accurate size of

some of them is not known and the figures given here

are probably very inaccurate.
