On which river would you find Victoria Falls?

Victoria Falls, or Mosi-oa-Tunya (Tokaleya Tonga: The Smoke That Thunders), is a waterfall in southern Africa on the Zambezi River at the border between Zambia and Zimbabwe. It has been described by CNN as one of the Seven Natural Wonders of the world.

David Livingstone, the Scottish missionary and explorer, is believed to have been the first European to view Victoria Falls on 16 November 1855, from what is now known as Livingstone Island, one of two land masses in the middle of the river, immediately upstream from the falls near the Zambian shore. Livingstone named his discovery in honour of Queen Victoria of Britain, but the indigenous Tonga name, Mosi-oa-Tunya—"The Smoke That Thunders"—continues in common usage as well. The World Heritage List officially recognizes both names.

The nearby national park in Zambia is named Mosi-oa-Tunya, whereas the national park and town on the Zimbabwean shore are both named Victoria Falls.

While it is neither the highest nor the widest waterfall in the world, Victoria Falls is classified as the largest, based on its combined width of 1,708 metres (5,604 ft) and height of 108 metres (354 ft), resulting in the world's largest sheet of falling water. Victoria Falls is roughly twice the height of North America's Niagara Falls and well over twice the width of its Horseshoe Falls. In height and width Victoria Falls is rivalled only by Argentina and Brazil's Iguazu Falls.
