The prickly dogfish (Oxynotus bruniensis) is a poorly known species of dogfish shark in the family Oxynotidae, inhabiting temperate Australian and New Zealand waters. Reaching a length of 75 cm (30 in), this brown to gray shark has a very thick body with a prominent "humpback" and extremely rough skin. It is further characterized by two enormous, sail-like dorsal fins placed relatively close together. Both dorsal fins have a spine embedded mostly within the fleshy leading portion of the fin; the first dorsal spine is tilted forward.

Found near the sea floor over outer continental and insular shelves and upper slopes, the prickly dogfish is thought to be a slow-moving predator of small benthic organisms. It is aplacental viviparous, with females giving birth to litters of around seven pups. This species is an uncommon bycatch of bottom trawls.
