River is a natural stream of freshwater that discharge or flow into oceans, seas, major lakes or desert basins. Rivers may have their source in a spring, lake, marsh or glacier. They are considered to be the main channels or largest tributaries of drainage systems. We all know that there are numerous rivers worldwide. So, let’s take a look at the longest rivers in the world.
Measuring the exact size of a river can be challenging due to different opinions on where origin and mouth of the rivers are actually located. Hence, the length measurements of many rivers are an approximation. But, for our list of longest rivers, we will go with what many scientists have agreed upon. Here are the ten longest rivers in the world.
1} Nile River:
Approximate Length: 6,650 km
Location: North East Africa
Source: White Nile
Nile is the longest river in the world. It flows Northward through Northeastern Africa to drain into the Mediterranean Sea. Its water resources are shared by eleven countries: Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, Sudan and Egypt. Nile is the primary water source of Egypt and Sudan.
2} Amazon River:
Approximate Length: 6,400 km
Location: South America

Second of the longest rivers in the world, Amazon has its mouth in the Atlantic Ocean on the Northeastern coast of Brazil. The Amazon basin is the largest drainage basin in the world. The portion of the river’s drainage basin in Brazil alone is larger than any other river’s basin. Amazon is sometimes called ‘The River Sea’ due to its vast dimensions.
3} Yangtze River:
Approximate Length: 6,300 km

Third of the longest rivers in the world, Yangtze has its mouth on the East China Sea. Yangtze is the border to ten provinces or regions. It has eight principal tributaries: Yalung River, Min River, Jialing River, Han River, Wu River, Yuan River, Xiang River and Gan River.
4} Mississippi – Missouri:
Approximate Length: 6,275 km

Fourth of the longest rivers in the world, Mississippi lies entirely with the United States of America. The river passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Missouri is the longest tributary of the Mississippi River and second longest in North America.
5} Yenisei River:

Approximate Length: 5,539 km
Location: Russia, Mongolia
Ranking fifth of the longest rivers in the world, Yenisei along with Angara and Selenga is the largest river system to flow into the Arctic Ocean. Rising in Mongolia, the river flows into Russia and drains in Kara Sea.
6} Yellow River:
Approximate Length: 5,464 km

Sixth of the longest rivers in the world, Yellow River or Huang He is the third-longest river in Asia. The river flows through nine provinces and its mouth in the Bohai Sea near the city of Dongying in Shandong province. The Yellow River is known as ‘the cradle of Chinese civilisation’, because its basin was the birthplace of ancient Chinese civilisation, and it was the most prosperous region in early Chinese history.
7} Ob River:
Approximate Length: 5,410 km
Location: Russia, Kazakhstan, China, Mongolia
Source: Katun River
Ranking seventh of the longest rivers in the world, Ob River is a major river in Western Siberia, Russia. It is the Westernmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two are Yenisei and Lena Rivers).
8} Parana River:
Approximate Length: 4,880 km
Location: Central Africa
Source: Paranaiba River
Eight of the longest rivers in the world, Parana River runs through Brazil, Paraguay and Argentina. The name Paraná derived from a phrase ‘para rehe onáva’ in Tupi language which means ‘like the sea’. It merges first with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean.
9} Congo River:
Approximate Length: 4,700 km
Location: Central Africa
Ninth of the longest rivers in the world, Congo River also known as Zaire River is world’s deepest river with measured depths in excess of 220 m. It crosses the equator twice. The Congo Basin has a total area of about 4 million square kilometer, or 13 per cent of the entire African landmass.
10} Amur River:
Approximate Length: 4,444 km
Location: Russia, China, Mongolia
Source: Onon River – Shilka River
Tenth of the longest rivers in the world, Amur River also known as Heilong Jiang forms border between Russia and China. The river rises in the hills of Western Manchuria at the confluence of its two major affluents, the Shilka River and the Ergune (or Argun) River.
