Peronopsis (meaning "broach-like" or possibly "boot-like") is a genus of trilobite restricted to the Middle Cambrian. Its remains have been found in Asia, Australia, Europe, and North America.

The subgenus Svenax is a contraction of Sven Axel, the given names of the paleontologist .

Peronopsis palmadon is intermediate between Peronopsidae and Condylopygidae, but it is not clear whether P. palmadon is ancestral to the Condylopigidae, a condylopigid exhibiting regression towards ancestral characters, or an example of parallel evolution.

These species may be assigned to one of the subgenera later or be reassigned to another genus.
