Centroberyx, often referred to as nannygais, is genus of ray-finned fishes found in the Indian Ocean and western Pacific Ocean, with the greatest species richness off southern Australia. They are reddish in colour and somewhat resemble the related soldierfish. Depending on species, they have a maximum length of 20 to 66 centimetres (7.9 to 26.0 in). They are found at depths of 10 to 500 metres (33 to 1,640 ft). Members of this genus are also known from fossils from the Cretaceous.
