Scaphohippus is an extinct Miocene genus of equine, with two known species, known from fossils found in California, New Mexico, Montana, and Nebraska.

The specimen was collected from fossiliferous layers of the Barstow Formation outcropping in Rodent Hill Basin, San Bernardino County, California.

While numerous specimens of isolated teeth and partial palates have been found at the type locality, comparatively few complete skulls are known.

The upper cheek teeth have a height of 40–50 mm at the mesostyle and the protocone connects with the protoconule after approximately 30% wear.

The type specimen for S. intermontanus is a section of jaw containing 6 teeth found in the Hemicyon Tuff, Barstow Formation, that outcrops in Hellgate Basin, San Bernardino County.
