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

Icelinus was first proposed as a monospecific genus in 1885 by the American ichthyologist David Starr Jordan with its only and type species being Artedius quadriseriatus.

[1] This species had been described in 1880 by the English zoologist William Neale Lockington from San Francisco.

[1] The genus Icelinus may not be monophyletic as a study found that the 9 eastern Pacific species were in a clade which was a sister taxon to the genera Furcina and Antipodocottus while the 2 northwestern Pacific species (I. japonicus and I. pietschi) were found to be so closely related to the genus Stlengis that they were placed within that genus, leaving Icelinus confined to the eastern Pacific.

[5] There are currently 11 recognized species in this genus:[6][7] Icelinus sculpins are characterised by having the fourth uppermost spine on the preoperculum having a number of points like the antler of a deer.
