Boyoma Falls, formerly known as Stanley Falls, consists of seven cataracts extending over 100 km on the Lualaba River near Kisangani (formerly Stanleyville) in the Democratic Republic of the Congo. At the bottom of the falls the Lualaba becomes the Congo River.

It is the world's highest-volume waterfall, seeing 17,000,000 liters of water rush by per second, with a total drop of 60 meters.
