Owenettidae is an extinct family of procolophonian parareptiles. Fossils have been found primarily from Africa and Madagascar, with one genus present from South America. It is the sister taxon to the family Procolophonidae.
The family was constructed in 1939 for the type genus Owenetta. Since then several other genera have been assigned to Owenettidae, including Barasaurus and Saurodektes. The oldest known owenettid, Owenetta rubidgei, dates back to the Wuchiapingian stage of the Late Permian. It and Saurodektes, have been found from the Beaufort Group in the Karoo Basin of South Africa, while Barasaurus is known from the Late Permian and the Early Triassic of Sakamena Group in Madagascar. These strata span the Permo-Triassic boundary and provide evidence for the great faunal change that occurred as a result of the Permian–Triassic extinction event. Although most owenettids lived during the Permian, remains of some taxa such as "Owenetta" kitchingorum (soon to be placed within its own genus) extend the temporal range of the family into the Triassic. The youngest known owenettid is Candelaria from the Santa Maria Formation of Brazil, which lived during the Ladinian stage of the Middle Triassic. The second youngest known owenettid, Ruhuhuaria, is known from the late Anisian Manda Beds of southwestern Tanzania.
