Brookvalia is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Middle Triassic epoch (Anisian stage).[2][1]

It contains four species, all known from the Hawkesbury Sandstone near Brookvale, New South Wales, Australia.[3][4]

  • B. gracilis Wade, 1933 (=B. parvisquamata Wade, 1933)
  • B. latipennis (Wade, 1935) (=Dictyopleurichthys latipennis Wade, 1935)
  • B. propennis Wade, 1933
  • B. spinosa (Wade, 1935) (=Beaconia spinosa Wade, 1935)

It was a member of the redfieldiiforms, a group of presumed basal neopterygians that were widespread during the Triassic.[5][6]
