Etjoia is an extinct genus of traversodontid cynodonts that lived during the Middle Triassic or Late Triassic period in southern Africa. This medium-sized omnivorous cynognathian provides important information on the dental evolution of early diverging gomphodonts and traversodontids.

==Discovery and etymology== Etjoia was discovered in the upper beds of the Omingonde Formation of Namibia (dated to the Ladinian to Carnian) by American paleontologist Charles Schaff in 1996. The specimen was unearthed on the south-eastern side of the Etjo Mountain, in the Waterberg Basin of the Otjozondjupa region, in central north-west Namibia. The holotype is deposited in the Geological Survey of Namibia of Windhoek with the specimen number GSN F1591. The generic name refers to Mount Etjo from which the new genus was unearthed. The type species, E. dentitransitus, refers to the possession of a transitional dentition with sub-circular upper postcanines and a large number of sectorial teeth representing the diademodontid/trirachodontid postcanine pattern, and with sub-rectangular lower postcanines with a mesially positioned transverse crest, which is the classical morphology of lower traversodontid postcanines.
