The Debate Over America’s Longest River

The question of which river is the longest in the United States has sparked debate among geographers and scientists for decades. While the Missouri River is often considered the longest, stretching approximately 2,341 miles, others argue that the Mississippi River, at roughly 2,340 miles, deserves the title when tributaries are included. This section dives into the complexities of measuring river lengths and the criteria used to determine the "longest."

What is the Length of the Missouri River?

The Missouri River is renowned as the longest river in the United States, measuring approximately 2,341 miles from its source in the Rocky Mountains of Montana to its confluence with the Mississippi River in St. Louis, Missouri.
