What Are the Biggest Rivers in the World?

4. Mississippi River

The Mississippi River flows for 2,320 miles, reaching the Gulf of Mexico near the bustling city of New Orleans. The Mississippi has long been significant to the continent’s indigenous peoples, but today it is still relied upon for water, fish, transportation, and even recreation. Many cities and towns have grown up on this river, including St. Louis, Missouri; Memphis, Tennessee; Minneapolis, Minnesota; and Natchez, Mississippi. Historically, the river formed the backdrop for major battles of the Civil War. It is also associated with steamboat travel, and many of these iconic vessels can still be seen floating on its waters.
