Pagetopsis is a genus of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes.

Pagetopsis was described as a genus in 1913 by the English ichthyologist Charles Tate Regan as a monotypic genus which had Champsocephalus macropterus, which had been described by the Belgian-born British ichthyologist George Albert Boulenger in 1907, as its only species.

[1] The genus name is a combination of opsis with Pagetodes, the name given by John Richardson in 1843 to an icefish frozen on the bow of HMS Terror which had been eaten by a cat before it could be preserved, Regan said that Pagetodes could not be used until that fish was rediscovered.

[2] There are currently two recognized species in this genus:[3] Pagetopsis has a forward curving spine on the snout and a slightly protruding lower jaw.

They are deep water demersal fishes which are at depths down to 800 m (2,600 ft).
