Which river is considered the longest in the world?

The Nile River is traditionally considered the longest river in the world, measuring approximately 6,650 kilometers (4,130 miles) in length. It flows northward through northeastern Africa, passing through several countries including Uganda, Sudan, and Egypt before emptying into the Mediterranean Sea. This river holds significant historical importance, supporting ancient civilizations and serving as a crucial water source in one of the world’s driest regions.

While the Amazon River is also a strong contender for this title and is sometimes referred to as the longest due to new measurements, the Nile has been recognized for centuries based on traditional methodologies. The Yangtze River, the longest river in Asia, and the Mississippi River, a major river in North America, are shorter than both the Nile and the Amazon.

Thus, the acknowledgment of the Nile as the longest river has been historically sustained and continues to be a reference point in geographical studies and discussions.
