This index covers 1,147 rivers from around the world, organized alphabetically for easy browsing. The selection includes waterways of every size, from short local streams to some of the longest rivers on Earth.

Rivers are natural flowing bodies of water that move from higher ground to lower ground, usually ending in an ocean, lake, or another river. They vary widely in length, width, and volume, ranging from narrow mountain creeks to vast systems that stretch across entire continents. Many rivers shape the land around them, carving valleys and depositing fertile soil along their banks. They also support drinking water, farming, transportation, and energy production for billions of people worldwide.

Interesting and little-known facts about Rivers: – The Nile and the Amazon are often debated as the longest river on Earth, depending on measurement methods. – Some rivers, like the Rio Negro, release so much tannin that their water appears black. – The Amazon River discharges more water than the next seven largest rivers combined. – A few rivers, including parts of the Okavango, never reach the sea and instead disappear into deserts or wetlands. – Underground rivers exist too, flowing beneath limestone caves in places like Mexico’s Yucatan Peninsula. – Some rivers change course naturally over decades, leaving behind old channels called oxbow lakes.
