Does the Mississippi River Flow Through Other Countries?

No. The Mississippi River flows entirely within the United States.

Course Summary

• Source: Lake Itasca, Minnesota (47° N).
• Length: ~3,766 km (2,340 mi) to Gulf of Mexico.
• States traversed/bordered (10): Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana.
• Watershed: Drains 3.2 million km² (41% of contiguous US), touching 31 states and 2 Canadian provinces (via tributaries like the Red River of the North)—but the main stem never leaves the US.

Common Confusion

The Mississippi River Basin extends into Canada (small headwater tributaries), but the river itself is 100% American. Contrast with the Rio Grande (US/Mexico border) or St. Lawrence (US/Canada).
