Ocepeia has been placed in various positions within the group of archaic mammals known as "condylarths" as successive discoveries yielded ever-more complete material.
On describing the more complete materials including new details of the skull anatomy, in 2014 Gheerbrant et al. placed Ocepeia in its own new, monotypic family-Ocepeiidae- based on its many uniquely derived traits (autapomorphies) and placed the family in an undetermined (and possibly new) order tentatively within Paenungulata.
