The world’s largest river depends on how you measure it. By volume and basin area, the Amazon River in South America is the largest, carrying more water than any other river on Earth. By length, the Nile River in Africa is the longest at about 6,650 km.
Rivers are the lifelines of civilizations. They shape landscapes, provide water for drinking and irrigation, support biodiversity, and inspire myths and legends. Among them, the question often arises: what is the world’s largest river?
The answer depends on how you measure “largest.” Some consider length, while others look at water volume, basin size, or depth. By length, the Nile River in Africa is often regarded as the longest. By discharge volume and basin area, the Amazon River in South America takes the crown.
In this detailed guide, we’ll explore the fascinating facts about the world’s largest rivers, compare the Amazon and Nile, and uncover interesting details about other mighty waterways across the globe.
Amazon vs Nile – Which Is the World’s Largest River?
One of the most debated topics in geography is the Amazon vs Nile comparison.
- Amazon River – The Amazon is the largest river in the world by volume. It discharges an average of 209,000 cubic meters of water per second into the Atlantic Ocean. Its drainage basin spans over 7 million square kilometers, making it the world’s largest watershed.
- Nile River – The Nile is considered the longest river in the world by length, stretching approximately 6,650 km (4,130 miles) from Burundi/Rwanda through Egypt into the Mediterranean Sea.
So which is the world’s largest river?
- By volume → Amazon wins.
- By length → Nile wins.
This distinction explains why different textbooks and resources sometimes list different answers.
Key Facts About the Amazon River
The Amazon River is unmatched when it comes to scale and biodiversity.
- Length: Around 6,400 km (3,980 miles)
- Basin area: 7 million sq. km (largest in the world)
- Discharge: Highest in the world (20% of Earth’s freshwater entering oceans)
- Biodiversity: Home to the Amazon rainforest, the most biodiverse ecosystem on Earth
- Countries it flows through: Peru, Colombia, Brazil
The Amazon is not only the largest river in the world by volume but also a vital artery of life for South America, supporting millions of people and countless wildlife species.
Key Facts About the Nile River
The Nile River is often called the “lifeline of Egypt.” For thousands of years, it has been central to civilizations along its banks.
- Length: 6,650 km (4,130 miles) → longest in the world
- Countries it flows through: Burundi, Rwanda, Uganda, South Sudan, Sudan, Egypt
- Basin area: 3.4 million sq. km
- Significance: Source of irrigation and agriculture for ancient and modern societies
While the Nile may not match the Amazon’s volume, its cultural and historical importance is unmatched.
Other Major Rivers in the World
Beyond the Amazon and Nile, several other rivers deserve recognition.
- Yangtze River (China): The longest river in Asia and the 3rd longest in the world, stretching 6,300 km.
- Mississippi-Missouri (USA): A river system extending about 6,275 km, vital for North American trade and agriculture.
- Ganga-Brahmaputra (India & Bangladesh): Sacred in Hinduism, this river system is crucial for millions of people.

World’s Largest Rivers by Different Criteria
When ranking rivers, different measures give different results:
- By Length: Nile (6,650 km)
- By Volume (discharge): Amazon (209,000 m³/s)
- By Drainage Basin: Amazon (7 million sq. km)
- By Depth: Congo River (~220 m) → deepest river in the world
- By Cultural Impact: Ganga and Nile stand out
This shows why the “largest” river title can’t be attributed to just one metric.
