1. Amazon River (South America)

• Length: ~6,400 km (4,000 mi)
• Discharge: 209,000 m³/s (largest by volume)
• Basin: 7.05 million km²
• Flows through Brazil, Peru, Bolivia, Colombia, Ecuador, Venezuela, Guyana.
• Powers the Amazon Rainforest, Earth's largest tropical forest.

2. Nile River (Africa)

• Length: ~6,650 km (4,132 mi) — traditionally considered the longest.
• Discharge: 2,830 m³/s
• Basin: 3.5 million km²
• Flows through 11 countries: Egypt, Sudan, South Sudan, Ethiopia, Uganda, Kenya, Tanzania, Rwanda, Burundi, DRC, Eritrea.
• Cradle of ancient Egyptian civilization.

3. Yangtze River (China)

• Length: ~6,300 km (3,917 mi) — Asia's longest.
• Discharge: 31,900 m³/s
• Basin: 1.8 million km²
• Flows entirely within China; empties into East China Sea at Shanghai.
• Three Gorges Dam is world's largest hydroelectric station.

4. Mekong River (Southeast Asia)

• Discharge: 16,000 m³/s
• Basin: 795,000 km²
• Flows through China, Myanmar, Laos, Thailand, Cambodia, Vietnam.
• Mekong Delta is a global rice bowl and biodiversity hotspot.

5. Niger River (West Africa)

• Length: ~4,167 km (2,589 mi)
• Discharge: 9,500 m³/s
• Basin: 2.12 million km²
• Flows through Guinea, Mali, Niger, Benin, Nigeria.
• Unique boomerang shape; inland delta in Mali is vital for agriculture and fisheries.

These rivers shape climates, civilizations, and economies across their basins.
