Bullichthys is an extinct genus of marine albuliform fish which existed in the Romualdo Formation, Brazil during the Early Cretaceous (Albian) period.

The genus name references its inflated otic bulla.

[1] It is thought to be one of the most basal members of the order Albuliformes, whose only extant relatives are the bonefish and gissus.
