Pteropterus is a genus of marine ray-finned fishes belonging to the family Scorpaenidae, the scorpionfishes. It is one of several genera in the subfamily Pteroinae which are colloquially referred to as "lionfish".

Taxonomy

The genus Pteropterus was described by William Swainson in 1839. In 1882, Joseph Swain synonymized Pteropterus with Pterois. Since then, Pteropterus has been inconsistently treated as either its own genus or a synonym of Pterois, until 2023, when it was validated after it was discovered that Pterois was not monophyletic.

Pteropterus is most closely related to the genus Dendrochirus.
