Had to think a bit to get Yukon. Adding that the length included portions in other countries helped. I was surprised to see that the Ohio was at the bottom of the list.

Why is the Mississippi river so popular and well known around the world when it isn't the biggest then?

It is. The length of the Missouri includes parts of the Mississippi because it is a tributary to the Mississippi.

The 2,341 mi does not include any part of the Mississippi River, so it is technically the longest. The Mississippi is the largest North American River system, though, which includes the Missouri (as well as the Arkansas, Red, and Ohio on this list) so that may be a big part of why it's more famous.

The Mississippi is probably more well known because its north-south course was the second natural western "boundary" (after the Appalachian Mountains) in the early days of the US. Also, the Mississippi was thought to be the longest river, before the Missouri was fully mapped - which happened later in US history.

Yup, and everything to the west of it was to be native land "as long as the grass grows and the rivers run," I think is how Andrew Jackson said it.

What are you trying to say? That Niger can't be the name of a country and the river that crosses it, as well?

What is the source for the lengths? Wikipedia says the Missouri is 2,341 miles, but gives 2,320 miles for the Mississippi - just slightly shorter than the Mississippi.

I live on the Wisconsin river. I thought it was one of the longest but guess not. Very pretty though😊

I grew up near the Potomac, which also fails to make the cut. Left column was easy for me. Right column less so.
