Helicolenus is a genus of marine ray-finned fishes belonging to the family Scorpaenidae where they are classified within the subfamily Sebastinae, the rockfishes.

The species in this genus are found in the Indian, Atlantic and Pacific oceans.

Helicolenus was described by a genus in 1896 by the American ichthyologists George Brown Goode & Tarleton Hoffman Bean using Scorpaena dactyloptera as its type species which had originally been described by the Genevan physician, naturalist, chemist, botanist and ichthyologist François Étienne Delaroche in 1809.

Their dorsal fins have 11-13 robust spines and 10 to 14 soft rays.

[6] Helicolenus rockfishes are commercially important species in fisheries in some regions such as southern Australia.
