Hypselohaptodus is a genus of sphenacodont synapsid from the Cisuralian of England. It contains a single species, Hypselohaptodus grandis, and is known only from a single specimen, a partial left maxilla, which is hosted at the . It was collected at Kenilworth, Warwickshire, England, from the (Warwickshire Group), dating to the earliest Asselian stage of the Cisuralian series, about 299  million years ago.[1]

H. grandis was originally assigned to Haptodus by Paton in 1974. In 2015 it was determined that H. grandis and Haptodus garnettensis were not congeneric with Haptodus baylei [2] and in 2019 Frederik Spindler reassigned H. grandis to a new genus, Hypselohaptodus.[3]
