Eggysodon is an extinct genus of odd-toed ungulate belong to the rhinoceros-like family Eggysodontidae. It was a small, ground-dwelling browser, and fossils have been found in Oligocene deposits throughout Europe.{{cite web | url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=43151 | title= Eggysodon | website=Paleobiology Database | access-date=28 October 2013}} Eggysodon may have been related to Preaceratherium, and both had tusklike canines and smaller, and fewer, incisors.

Allacerops (=Teniseggysodon), a close relative of Eggysodon, was synonymized with Eggysodon by Heissig (1989), but is now considered a distinct genus.Heissig, K., 1989. Rhinocerotidae. In D. R.
