The Roubidoux Spring is a freshwater spring in Waynesville, Missouri.  It discharges from the base of a rock ledge and flows only about 140-feet to the Roubidoux Creek.

The spring's rock ledge has a concrete wall to not only protect the spring, but to support Spring Road which nearly runs over-top of the spring.

The Spring is estimated to have an average discharge of around 436-gallons of water per second.
