Onykia robsoni, the rugose hooked squid, is a species of squid in the family Onychoteuthidae. It occurs in the Antarctic Ocean, at an estimated depth of 250–550 meters. The mantle of this species grows to a length of 75 cm. The species has been suggested as a junior synonym of Onykia carriboea, the tropical clubhook squid, due to similarities between the species.
