The Rio Grande is often classified as either the fourth or fifth longest river system in North America, primarily due to its length of approximately 1,896 miles. Its ranking can vary depending on how river systems are measured, as some sources include tributaries or consider the Missouri River system, which is longer when combined with its tributaries. Additionally, the definition of river length can differ based on the starting and ending points used in calculations. This variability in measurement criteria leads to differing rankings within the context of North American river systems.
