Desmostylidae is an extinct family of herbivorous marine mammals belonging to the order of Desmostylia. They lived along the coast of the northern Pacific Ocean from the Early Oligocene (Rupelian) through the Late Oligocene (Chattian) (33.9 mya—23.0 Mya) existing for approximately .
==Taxonomy and systematics==
Desmostylidae was named by . It was assigned to Sirenia by Osborn (1905); to Proboscidea by Abel (1919); to Desmostyliformes by Simpson (1932), Kretzoi (1941) and Reinhart (1959); to Desmostylia by McKenna and Bell (1997); and to Desmostylia by Carroll (1988), Inuzuka et al. (1995), Inuzuka (2000) and Barnes and Goedert (2001).〔. Retrieved May 2013.〕
found an subadult specimen of ''Behemotops proteus'' on Vancouver Island in 2007. They noted that (1) the cranial features of their specimen were similar to those of ''Cornwallius'' and that (2) the adult dentition was not delayed in their specimen, unlike in ''Desmostylus'' and other Afrotheria, and they concluded that (1) Desmostylidae and Paleoparadoxiidae probably diverged earlier than previously believed and that (2) delayed dentition can not be the most primitive state of Desmostylia.
