The Amazon River is the second longest river (it is just shorter than the Nile River in Egypt) in the world and it has the largest watershed or drainage basin as well as the most tributaries of any river in the world. For reference, a watershed is defined as the area of land that releases its water into a river. This entire area is often referred to as the Amazon Basin. The Amazon River begins with streams in the Andes Mountains in Peru and flows into the Atlantic Ocean about 4,000 miles (6,437 km) away.

The Amazon River and its watershed encompass an area of 2,720,000 square miles (7,050,000 sq km). This area includes the largest tropical rainforest in the world - the Amazon Rainforest. In addition parts of the Amazon Basin also include grassland and savannah landscapes. As a result, this area is some of the least developed and most biodiverse in the world.

Along its length, the Amazon River flows through three countries and its basin includes three more. The following is a list of these six countries that have claims to the Amazon region arranged by their area. For reference, their capitals and populations have also been included. All information was obtained from the CIA World Factbook .
