Pediolophodon is an extinctgomphotheriidproboscidean genus[1] from the middle to lateMiocene of North America (Nebraska andTexas).Pediolophodon was a close relative of elephants (members of theElephantinae subfamily ofElephantidae) and would have appeared superficially similar to them, but was not itself a true elephant.

Two species are recognized,P. campester andP. fricki. Both were originally assigned to the Old World genusTetralophodon, but discoveries in the Kepler Quarry, Nebraska, showed these taxa to be generically distinct.[2][3][1]
