Hypsocormus (from Greek: ῠ̔́ψος húpsos, 'height' and Greek: κορμός kormós 'timber log') is a genus of pachycormiform from the Jurassic with fossils being found in Germany, France and the United Kingdom. The two species are H. insignis and H. posterodorsalis.
Hypsocormus was about 1 m (3.3 ft) long, with a caudal fin just like a mackerel. It had a dorsal fin, long pectoral fins and tiny pelvic fins.
In 1860, Johann Andreas Wagner discovered the type species, H. insignis. The species was then placed into this genus. For a long time, it has been considered to be the only species of Hypsocormus. However, in 2020, Maxwell and others described a new species, H. posterodorsalis. There are currently two species in this genus.
