Rhamphochromis lucius is a species of piscivorous cichlid endemic to Lake Malawi where it prefers deep, open waters.

This species can reach a length of 40 centimetres (16 in) TL.

It can also be found in the aquarium trade.

[1] FishBase treats this species as a valid species, although note that it may be a synonym of Rhamphochromis woodi but the Catalog of Fishes treats it as a synonym of Rhamphochromis esox,[2] as does the IUCN.
