The World's Longest Rivers

At 6,400 km, the Amazon carries more water than any other river on Earth — about 20% of all freshwater that flows into the world's oceans, which is 60% more than the runner-up, the Congo. Its basin contains the largest tropical rainforest on the planet.

China's longest river at 6,300 km is the third longest in the world, shorter than the Nile by 350 km. The Three Gorges Dam on the Yangtze is the world's largest hydroelectric power station, generating 85 terawatt-hours of electricity annually for hundreds of millions of people.

Measured from the Missouri's headwaters, this system reaches 6,275 km, making it longer than the Yangtze by 25 km. The Mississippi alone drains 41% of the continental United States and has shaped American culture, commerce, and mythology for centuries.

The Yenisei system in Siberia stretches 5,539 km from Mongolia to the Arctic Ocean. It drains the largest catchment of any river flowing into the Arctic and carries the most water of any river in Asia — a volume that outperforms the Amazon, the world's largest river by discharge, in its region. With an average flow of 19,600 cubic meters per second, it carries more water than the #4 Congo, which has a significantly smaller discharge.

At 5,464 km, the Yellow River is known as "the cradle of Chinese civilization" — the Yellow River basin was the birthplace of ancient Chinese culture. Its silty waters have built the North China Plain over millennia, and it carries the highest sediment load of any river globally, averaging 1.6 billion tons per year — that's over 30 times more than the #7 Yenisei–Angara. It is also nearly 800 km longer than the #4 Congo, making it the world's sixth longest river.

The Ob system in western Siberia runs 5,410 km from the Altai Mountains to the Arctic Ocean. Its basin covers 2.99 million square kilometres, making it one of the largest drainage basins in the world — just slightly smaller than that of the #7 Yenisei–Angara but larger than the basin of the #4 Congo. At its peak, the Ob's discharge exceeds 12,000 cubic meters per second, outpacing the average flow of the Yellow River by more than tenfold.

At 4,700 km, the Congo is Africa's second longest river but its deepest — reaching over 220m in places, making it over four times deeper than the #7 Yenisei–Angara. It drains the Congo Basin, the second largest tropical rainforest in the world after the Amazon, covering an area of 3.7 million square kilometres. With a discharge of 41,000 cubic meters per second, it is the world's second largest river by volume, trailing only the Amazon.

At 4,444 km, the Amur forms the border between Russia and China for much of its length, making it 12% shorter than the #5 Mekong but still ranking as the world's tenth longest river. It's one of the least modified major rivers in the Northern Hemisphere, with only 7% of its basin dammed, compared to the Yangtze's 50%.

The Lena in Siberia runs 4,400 km from the Baikal Mountains to the Arctic Ocean, 8% longer than the Volga but 2% shorter than the Amur–Argun. It is largely untouched by human development; in winter, it freezes solid and serves as a road for vehicles in remote regions, supporting over 200,000 people annually via this ice highway.
