Nautichthys is a genus of marine ray-finned fishes. They are the only members of the family Nautichthyidae, the sailfin sculpins.23 These fishes are found in the North Pacific Ocean.

They were previously placed in the subfamily Hemitripterinae which is part of the family Agonidae, but a 2026 study found it to form a distinct clade together with Hemilepidotus and Hemitripteridae, and morphologically distinct enough to deserve its own family.23
