Elliotsmithia is a small varanopid synapsid found from the late Middle Permian of South Africa. It is the sole basal synapsid "pelycosaur" known from the supercontinent Gondwana and only two specimens have been yielded to date. Its species name longiceps is derived from Latin, meaning "long head". Both known Elliotsmithia fossils were recovered from Abrahamskraal Formation rocks—within the boundaries of the Tapinocephalus Assemblage Zone—of the lower Beaufort Group. It was named for the late Sir Grafton Elliot Smith in 1937.

== History of discovery== In 1917 Dr. Van Hoepen discovered the fossil holotype of Elliotsmithia. The holotype consisted of a skull, mandibles with most of the front region missing, the first four cervical vertebrae complete with atlas-axis complex, rib fragments, and dermal ossifications. Van Hoepen found the fossil in rocks associated with the Tapinocephalus Assemblage Zone near the town Prince Albert in the Western Cape. The specimen remained undescribed until renowned paleontologist and physician, Dr. Robert Broom, briefly described and named the fossil in 1937. However, Broom did not go into great detail in his description. Several researchers authored papers over several decades, providing passing descriptions of the fossil. In the 1990s, renewed research on the holotype fossil classified Elliotsmithia as a varanopseid "pelycosaur" synapsid. Another specimen was found in 2001.
