Setting the Record Straight: The St. Johns River Flows Northwesterly, Not North

Correcting a Common Misconception

Contrary to popular belief, the St. Johns River does not flow due north. It runs northwesterly from its headwaters in Indian River County to the Atlantic Ocean near Jacksonville, Florida.

Why the Confusion?

Its general northerly trend and the rarity of north‑flowing rivers in the U.S. fuel the myth. In reality, the river’s course is shaped by subtle elevation gradients across Florida’s flat terrain.
