What is the common name of the waterfall on the Zambezi River known as 'Mosi-oa-Tunya'?

The waterfall on the Zambezi River known as Mosi-oa-Tunya is Victoria Falls.

Victoria Falls lies on the border between Zambia and Zimbabwe, where the Zambezi River plunges across a broad basalt plateau into a narrow gorge. The Lozi name Mosi-oa-Tunya is commonly translated as “The Smoke That Thunders,” describing the roar and towering spray produced by the falling water.

The falls form a curtain about 1,708 metres wide and reach a maximum height of roughly 108 metres. During the river's high-water season, spray can rise hundreds of metres and create vivid rainbows. At low water, rocky islands divide the crest into named sections, including the Main Falls, Rainbow Falls, and Eastern Cataract.

Local communities knew the falls long before European exploration. Scottish missionary David Livingstone became the first recorded European to view them in 1855 and popularised the name Victoria Falls in honour of Queen Victoria. Mosi-oa-Tunya remains an official and widely used name, so the two names refer to the same natural landmark—not separate waterfalls. The site is also recognised as a UNESCO World Heritage property.
