Iron Mike is an 1896 cast-iron fountain in the 400 Block of Washington Street in the city of Oregon, Illinois.

The fountain's lowest tier is a pool for pets and reads "Illinois Humane Society."

On the rear side of the horse basin is a "bubbler" for adults, it is also reachable by children via the iron step.

The multi-tier fountain was originally set into a concrete base which was immediately adjacent to the curb of Route 64.

In 2021 Iron Mike was relocated 15 feet away from the road unto the property of the Ogle County Courthouse.
