Odobenidae is a family of pinnipeds, of which the only extant species is the walrus (Odobenus rosmarus). In the past, however, the group was much more diverse, and includes more than a dozen fossil genera.

In re-analyzing Pelagiarctos, Boessenecker et al. (2013) proposed the phylogenetic relationships of Odobenidae as follows (this analysis excluded Archaeodobenus, Titanotaria, Nanodobenus, and Pliopedia; and included Enaliarctos, Pteronarctos, Allodesmus, Desmatophoca, Callorhinus, Monachus, and Erignathus):[3]
