Porocottus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins.

These fishes are found in the northern and northwestern Pacific Ocean.

Porocottus was first proposed as a monospecific genus in 1859 by the American biologist Theodore Gill[1] when he described Porocottus quadrifilis from the Bering Strait.

[2] The 5th edition of Fishes of the World classifies the genus Artediellus within the subfamily Cottinae of the family Cottidae,[3] however, other authors classify the genus within the subfamily Myoxocephalinae of the family Psychrolutidae.

[1] There are currently nine recognized species in this genus:[4]
