Nanodobenus arandai is an extinct pinniped of the walrus family Odobenidae that lived during the Miocene in what is now Baja California Sur, Mexico. It is known from a partially complete left mandible and a right calcaneum bone. Like other early members of the family it looked more like a modern fur seal or sea lion than a walrus and lacked the long tusks of walruses. Individuals were probably around 1.65 metres long, which makes Nanodobenus the smallest known member of the walrus family and suggests that it filled a different niche from the larger odobenids that lived at the same time. It is a relatively basal species of odobenid.
