World Rivers Quiz
The Nile, the Amazon, the Yangtze and 17 more: find the major rivers of the world on the map, type them from memory, or learn them first.
Every river is labelled. Tap or click one (or pick it from the list) to see its length, where it starts and ends, and the countries it flows through. Zoom in to see every name.

Sources and notes
Rivers are drawn from Natural Earth’s 1:10m rivers and lake centerlines (public domain), with its European and North American supplements: each river’s named pieces are joined into one line from its source to its mouth, including where it runs through a lake. Tributaries are separate rivers, so the Missouri and the Mississippi, or the Blue Nile and the Nile, are drawn and named on their own.
River lengths depend on where you put the source and the mouth, and on how closely you follow the bends, so books disagree. The lengths here come from one source per river, each checked against at least one other reference or national agency: the CIA World Factbook where it lists the river and the others agree (the source the 10 longest rivers quiz uses), the US Geological Survey for rivers of the United States, and for the rest the river’s Wikipedia article or, where it publishes one, the river basin commission’s or water agency’s figure.
The Nile and the Amazon are the two longest rivers, and which one is longer is still argued. The World Factbook puts the Nile first (6,650 km against the Amazon’s 6,436 km); some studies that measure the Amazon from a more distant source in Peru put it ahead.
Some rivers are counted as systems in lists of the longest: the Mississippi–Missouri (6,275 km), the Yenisei–Angara (5,539 km) and the Ob–Irtysh (5,410 km). Here each river has its own length, so the Mississippi alone is shorter than the system it belongs to.
Other names count: the local name or an old spelling (Chang Jiang, Huang He, Ganga, Dnipro, Wisła), and you can add or leave out “River” or “Rio”.
Find on the map: we name a river, you click its line or its dot. Practice gives you three tries and highlights the right part of the map after two misses; Test gives you three tries without hints; Strict gives you one. After the last miss, the river is shown and the next one comes up.

About these 20 rivers
The list starts with the ten longest river systems in the world, one river each: the Nile, Amazon, Yangtze, Mississippi, Yenisei, Yellow River, Ob, Congo, Amur and Lena. The Paraná, South America’s second river, comes next.
Then come the rivers every atlas labels and every school course names: the Mekong, Ganges and Indus in Asia, the Niger and Zambezi in Africa, the Danube, Rhine and Volga in Europe and the Murray in Australia. Every continent but Antarctica has at least one.
