Eubelodon is an extinct genus of gomphothere (a family in the order Proboscidea, which also includes modern elephants) which lived in North America during the Miocene Epoch.

It has the highly unusual combination of retaining a long lower jaw, but having lost the lower tusks, a combination only shared with fellow North American gomphothere Gnathabelodon and the choerolophodontid Choerolophodon.

[1] Fossils are restricted to what is now the Great Plains of the United States.

It was synonymized subjectively with Trilophodon by Osborn in 1918 and again by Tobien in 1973 with Gomphotherium.
