Trematosaurinae is a subfamily of temnospondyl amphibians within the family Trematosauridae.

Like all trematosaurids, they were marine piscivores, resembling crocodiles in their general build.

Unlike the long, almost gharial-like snouts of the Lonchorhynchinae, the Trematosaurinae had more "normal" crocodile-like skulls.
