Here are the top 5 longest rivers in the world, ordered by their total length. Note that the length of a river can be difficult to measure, as it may have multiple branches, tributaries, and changing water levels throughout the year. Therefore, the length of these rivers is approximate.
- Nile River: 6,650 km
- Amazon River: 6,400 km
- Yangtze River: 6,300 km
- Mississippi-Missouri River System: 6,275 km

The river itself is fed by over 1,000 tributaries, with the largest being the Madeira, Purus, and Negro rivers. The Amazon carries more water than any other river, accounting for roughly one-fifth of the world’s total river flow, and is responsible for up to 20% of the world’s total freshwater discharge into the ocean.
- The Yangtze River, also known as the Chang Jiang, is the longest river in Asia and the third-longest river in the world, with a total length of approximately 6,300 kilometers.
