Although the Ucayali–Marañón confluence is the point at which most geographers place the beginning of the Amazon River proper, in Brazil the river is known at this point as the ''[[Solimões]] das Águas''. The river systems and flood plains in Brazil, Peru, Ecuador, Colombia, and Venezuela, whose waters drain into the ''Solimões'' and its tributaries, are called the "Upper Amazon".

The Amazon proper runs mostly through Brazil and Peru, and is part of the border between Colombia and Peru. It has a series of major tributaries in [[Colombia]], [[Ecuador]] and [[Peru]], some of which flow into the [[Marañón River|Marañón]] and [[Ucayali]], and others directly into the Amazon proper. These include rivers [[Putumayo River|Putumayo]], [[Caquetá River|Caquetá]], [[Vaupés River|Vaupés]], [[Rio Negro (Amazon)|Guainía]], [[Morona]], [[Pastaza River|Pastaza]], Nucuray, Urituyacu, [[Chambira River|Chambira]], [[Tigre River|Tigre]], [[Nanay River|Nanay]], [[Napo River|Napo]], and [[Huallaga River|Huallaga]].

At some points, the river divides into [[anabranch]]es, or multiple channels, often very long, with inland and lateral [[Stream channel|channels]], all connected by a complicated system of natural canals, cutting the low, flat ''igapó'' lands, which are never more than {{cvt|5|m|sp=us}} above low river, into many islands.{{sfn|Church|1911|p=788}}

From the town of Canaria at the great bend of the Amazon to the Negro, vast areas of land are submerged at high water, above which only the upper part of the trees of the sombre forests appear. Near the mouth of the Rio Negro to Serpa, nearly opposite the river Madeira, the banks of the Amazon are low, until approaching Manaus, they rise to become rolling hills.{{sfn|Church|1911|p=789}}
