The 'Brisbane River cod' is a form of ''Maccullochella'' cod that occurred naturally in the Brisbane River system, an east coast river system in south east Queensland, Australia. Their exact taxonomic status is not known.
All naturally occurring ''Maccullochella'' cod in east coast drainages ultimately originate from Murray cod, ''Maccullochella peelii peelii'', that crossed the Great Dividing Range and entered east coast drainages from one or more natural river capture events.
Brisbane River cod are extinct, from overfishing, habitat destruction and siltation, and whole-of-catchment scale bushfires and ash fish kills in the 1930s.
The Brisbane River has now been restocked with Mary River cod from the Mary River system.
