Zambezi
Fourth-longest African river, largest east-flowing into the Indian Ocean.
The Zambezi (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa, and the largest flowing into the Indian Ocean from Africa. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it empties into the Indian Ocean. The Zambezi's most noted feature is Victoria Falls, and it also includes Chavuma Falls and Ngonye Falls.

Lore & Background
The area around the source is a national monument, forest reserve, and important bird area. It re-enters Zambia, dropping about 400 m in elevation from its source to Chavuma Falls, and then flows through a wide floodplain studded with Borassus fan palms, eventually reaching the Barotse Floodplain, a notable feature of the upper Zambezi. The Victoria Falls mark the boundary between the upper and middle Zambezi. Below the falls, the river cuts through perpendicular walls of basalt in the Batoka Gorge, described as one of the world's most spectacular whitewater trips. The lower Zambezi, from Cahora Bassa to the Indian Ocean, is navigable for 650 km, though shallow in many places during the dry season. The river splits into a delta near the ocean, with primary distributaries including Kongone, Luabo, Timbwe, and the Chinde mouth.
Reader's Guide
The Zambezi River is significant as a major waterway in southern Africa, providing hydroelectric power through the Kariba Dam (serving Zambia and Zimbabwe) and the Cahora Bassa Dam (serving Mozambique and South Africa), as well as smaller power stations at Victoria Falls and Zengamina in Zambia. The river's annual flood cycle dominates the natural environment and human life along the Barotse Floodplain, influencing the culture of the Lozi people, whose annual move from Lealui to Limulunga is celebrated as the Kuomboka festival. The construction of the Kariba and Cahora Bassa dams has controlled seasonal variations in flow, reducing the delta's width by about half and altering the delivery of nutrient-rich fresh water to coastal wetlands. The Zambezi's Victoria Falls is its most noted feature, and the river's rapids and gorges offer significant challenges for kayakers and rafters.
Did You Know?
- The Zambezi is the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa.
- The river rises in a black, marshy dambo in dense miombo woodland in the Ikelenge District of North-Western Province, Zambia.
- The delta of the Zambezi is today about half as broad as it was before the construction of the Kariba and Cahora Bassa dams.
Frequently Asked Questions
Who is Zambezi?
Zambezi is a major African river that ranks as the continent's fourth-longest waterway. It holds the distinction of being the longest river in Africa that flows eastward, and it is the biggest African river that delivers its waters to the Indian Ocean.
What is Zambezi's route across the continent?
The river begins its journey in Zambia before threading through eastern Angola, skirting the northeastern edge of Namibia, and tracing the northern boundary of Botswana. It then runs along the shared border of Zambia and Zimbabwe before finally reaching Mozambique.
What are Zambezi's most notable features?
Victoria Falls is by far the river's most famous landmark, though Chavuma Falls and Ngonye Falls are also significant drops along its course. Two major dams—Kariba and Cahora Bassa—regulate flows at key points downstream.
How does Zambezi's story end?
After passing through six countries, the river empties into the Indian Ocean within Mozambique's territory. That estuary marks the final chapter of a journey that began in the highlands of Zambia.
Why is Zambezi important to the region?
Spanning six nations—Zambia, Angola, Namibia, Botswana, Zimbabwe, and Mozambique—it serves as a vital waterway and natural border for all of them. Its status as Africa's largest east-flowing river and its dramatic waterfalls make it both an ecological and a cultural cornerstone.
