This is a list of rivers of the Americas, it includes major historical or physiological significant rivers of the Americas grouped by region where they are located (Central America, Northern America, West Indies and South Americas). The longest rivers in each country are included. Further details and references are provided in each river's separate article. Unusually significant tributaries appear in this list, under the river into which they drain.
The longest river in the Americas is the Amazon River. The length of the Amazon River is usually said to be "at least" 6,400 km (4,000 mi),[1] but reported values lie anywhere between 6,275–7,025 km (3,899–4,365 mi).[2] The length measurements of many rivers are only approximations and differ from each other because there are many factors that determine the calculated river length, such as the position of the geographical source and the mouth, the scale of measurement, and the length measuring techniques (for details see also List of rivers by length).[2][3]
There are 11 countries in the Americas that do not have rivers: Anguilla,[4] Aruba, Bermuda,[5] Bonaire, Cayman Islands,[6] Curaçao, Saba, Saint Barthélemy, Saint Martin, Sint Eustatius, and Sint Maarten.
