Hemisaurida is an extinct genus of prehistoric marine aulopiform ray-finned fish, known from Late Cretaceous fossils found in Europe and the Middle East.

The following species are known:

Previously placed in the family Halecidae, more recent studies have found it to likely not belong to that family, and it may occupy a more basal position within the Enchodontoidei.
