2,293,412 km (2017)

top ten longest rivers:

• Nile (Africa) 6,693 km;
• Amazon (South America) 6,436 km;
• Mississippi-Missouri (North America) 6,238 km;
• Yenisey-Angara (Asia) 5,981 km;
• Ob-Irtysh (Asia) 5,569 km;
• Yangtze (Asia) 5,525 km;
• Yellow (Asia) 4,671 km;
• Amur (Asia) 4,352 km;
• Lena (Asia) 4,345 km;
• Congo (Africa) 4,344 km

note 1: rivers are not necessarily navigable along the entire length; if measured by volume, the Amazon is the largest river in the World, responsible for about 20% of the Earth's freshwater entering the ocean

note 2: there are 20 countries without rivers: 3 in Africa (Comoros, Djibouti, Libya); 1 in the Americas (Bahamas); 8 in Asia (Bahrain, Kuwait, Maldives, Oman, Qatar, Saudi Arabia, United Arab Emirates, Yemen); 3 in Europe (Malta, Monaco, Holy See), 5 in Oceania (Kiribati, Marshall Islands, Nauru, Tonga, Tuvalu); these countries also do not have natural lakes

top ten largest natural lakes (by surface area):

• Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan) 372,960 sq km;
• Lake Superior (Canada, United States) 82,414 sq km;
• Lake Victoria (Kenya, Tanzania, Uganda) 69,490 sq km;
• Lake Huron (Canada, United States) 59,596 sq km;
• Lake Michigan (United States) 57,441 sq km;
• Lake Tanganyika (Burundi, Democratic Republic of the Congo, Tanzania, Zambia) 32,890 sq km;
• Great Bear Lake (Canada) 31,800 sq km;
• Lake Baikal (Russia) 31,494 sq km;
• Lake Nyasa (Malawi, Mozambique, Tanzania) 30,044 sq km;
• Great Slave Lake (Canada) 28,400 sq km

note 1: the areas of the lakes are subject to seasonal variation; only the Caspian Sea is saline, the rest are fresh water

note 2: Lakes Huron and Michigan are technically a single lake because the flow of water between the Straits of Mackinac that connects the two lakes keeps their water levels at near-equilibrium; combined, Lake Huron-Michigan is the largest freshwater lake by surface area in the World

note 3: the deepest lake in the world (1,620 m), and also the largest freshwater lake by volume (23,600 cu km), is Lake Baikal in Russia
