World's Longest River

1. Amazon (6,992KM)

Amazon River The Amazon River, usually abbreviated to Amazon in South America is the largest river by discharge volume of water in the world, and according to some authors, the longest. At an average discharge of about 209,000 cubic meters per second (7,400,000 cu ft/s; 209,000,000 L/s; 55,000,000 USgal/s) approximately 6,591 cubic kilometers per annum (1,581 cubic mi/a), greater than the next seven largest independent rivers combined the Amazon represents 20% of the global riverine discharge to the ocean. The Amazon basin is the largest drainage basin in the world, with an area of approximately 7,050,000 square kilometers (2,720,000 sq mi). The portion of the river’s drainage basin in Brazil alone is larger than any other river basin. The Amazon enters Brazil with only one-fifth of the flow it finally discharges into the Atlantic Ocean, yet already has a greater flow at this point than the discharge of any other river.

2. Nile (6,853KM)

Nile River The Nile is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, however other conflicting sources cite a 2007 study that gave the title to the Amazon River in South America. The Nile, which is 6,853 km (4,258 miles) long, is an “international” river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.

3. Yangtze (6,300KM)

Yangtze River The Yangtze, known in China as the Ch ng Jing or the Yangz Jing, is the longest river in Asia and the third-longest in the world. The river is the longest in the world to flow entirely within one country. It drains one-fifth of the land area of the People’s Republic of China (PRC) and its river basin is home to one-third of the country’s population. The Yangtze is the sixth-largest river by discharge volume in the world.

4. Mississippi (6,275KM)

Mississippi River The Mississippi River is the chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system. Flowing entirely in the United States (although its drainage basin reaches into Canada), it rises in northern Minnesota and meanders slowly southwards for 2,320 miles (3,730 km) to the Mississippi River Delta at the Gulf of Mexico. With its many tributaries, the Mississippi’s watershed drains all or parts of 31 U.S. states and 2 Canadian provinces between the Rocky and the Appalachian Mountains. The Mississippi ranks as the fourth longest and fifteenth largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.

5. Yenisei River (5,539KM)

Yenisei River The Yenisei also Romanized Yenisey, Enisei, Jenisej, is the largest river system flowing to the Arctic Ocean. It is central of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Lena). Rising in Mongolia, it follows a northerly course to the Yenisei Gulf in the Kara Sea, draining a large part of central Siberia, the longest stream following the Yenisei-Angara-Selenga-Ider river system. The maximum depth of the Yenisei is 24 meters (80 ft) and the average depth is 14 meters (45 ft). The depth of river outflow is 32 meters (106 ft) and inflow is 31 meters (101 ft).

6. Yellow River (5,464KM)

Yellow River The Yellow River or Huang He is the third-longest river in Asia, after the Yangtze River and Yenisei River, and the sixth-longest river system in the world at the estimated length of 5,464 km (3,395 mi). Originating in the Bayan Har Mountains in Qinghai province of western China, it flows through nine provinces, and it empties into the Bohai Sea near the city of Dongying in Shandong province. The Yellow River basin has an east-west extent of about 1,900 kilometers (1,180 mi) and a north-south extent of about 1,100 km (680 mi). Its total drainage area is about 752,546 square kilometers (290,560 sq mi).

7. Ob River (5,410KM)

Ob River The Ob River is a major river in western Siberia, Russia and is the world’s seventh-longest river. It forms at the confluence of the Biya and Katun Rivers which have their origins in the Altay Mountains. It is the westernmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Yenisei River and the Lena River). The Gulf of Ob is the world’s longest estuary.

8. Paran River (4,880KM)

The Paran River is a river in south Central South America, running through Brazil, Paraguay, and Argentina for some 4,880 kilometers (3,030 mi). It is second in length only to the Amazon River among South American rivers. The name Paran is an abbreviation of the phrase “para rehe on va”, which comes from the Tupi language and means “like the sea” (that is, “as big as the sea”). It emerges first with the Paraguay River and then farther downstream with the Uruguay River to form the R o de la Plata and empties into the Atlantic Ocean.

9. Congo River (4,700KM)

Congo River The Congo River (also known as the Zaire River) is the second-longest river in Africa after the Nile and the second largest river in the world by discharge volume of water (after the Amazon), and the world’s deepest river with measured depths over 220 m (720 ft). The Congo-Chambeshi river has an overall length of 4,700 km (2,920 mi), which makes it the ninth-longest river (in terms of discharge, the Chambeshi is a tributary of the Lualaba River, Lualaba being the name of the Congo River upstream of the Boyoma Falls, extending for 1,800 km). Measured along the Lualaba, the Congo River has a total length of 4,370 km (2,715 mi). It crosses the equator twice. The Congo Basin has a total area of about 4 million square kilometers or 13% of the entire African landmass.

10. Amur River (4,444KM)

Amur River The Amur River or Heilong Jiang is the world’s tenth longest river, forming the border between the Russian Far East and Northeastern China. The largest fish species in the Amur is the Kaluga, attaining a length as great as 5.6 meters (18 ft). The Amur River is the only river in the world in which subtropical Asian fish such as snakehead, coexist with Arctic Siberian fish, such as pike. The river is home to a variety of other large predatory fish such as Taimen, Amur Catfish, and yellow cheek.
