Lumkuia is an extinct genus of cynodont, fossils of which have been found in the Cynognathus Assemblage Zone of the Beaufort Group in the South African Karoo Basin that date back to the early Middle Triassic. It contains a single species, Lumkuia fuzzi, which was named in 2001 on the basis of the holotype specimen BP/1/2669, which can now be found at the Bernard Price Institute in Johannesburg, South Africa. The genus has been placed in its own family, Lumkuiidae. Lumkuia is not as common as other cynodonts from the same locality such as Diademodon and Trirachodon.

== Discovery and naming == The holotype and only known specimen of Lumkuia, BP/1/2669, was found by Paul Reubsamen near the Lumku Mission in the Eastern Cape province, close to the small town of Lady Frere. It was collected from rocks belonging to the subzone B of the Cynognathus Assemblage Zone. It consists of a well-preserved skull, part of the shoulder girdle (including the left scapulocoracoid, the left and a partial right clavicle, and the interclavicle), 10 dorsal vertebrae with ribs, 8 caudal (tail) vertebrae, and a nearly complete left forelimb. The specimen was stored in the fossil collection of the Bernard Price Institute of Johannesburg, where it was originally listed as a juvenile of Trirachodon, a basal member of Gomphodontia. However, in 1988 the American palaeontologist James A. Hopson noted several traits that it shared with Probainognathus and the chiniquodontids, members of a more mammal-like clade of cynodonts that would later be named Probainognathia.
