Hypsognathus ('high jaw') is an extinct genus of procolophonid parareptile from the Late Triassic of New Jersey and Connecticut.

Hypsognathus resembled a moderately sized lizard, with a length of 33 centimetres (13 in), although it was unrelated to modern lizards. Because of its broad teeth, Hypsognathus is thought to have been a herbivore. Its body is low and broad and it has a relatively short tail. Hypsognathus has some spikes on the side of its head, probably for protection against predators.
