Heterobranchus boulengeri is a species of airbreathing catfish found in the Democratic Republic of the Congo, Zambia and Zimbabwe.

The fish is named in honor of ichthyologist-herpetologist George A. Boulenger (1858-1937), of the British Museum (Natural History), who had described many of the fishes from Central Africa and the Congo River system.

This species can reach 64.0 cm (25.2 inches) TL in length.

[3] Heterobranchus boulengeri is found in tropical freshwater rivers and lakes.

It is demersal, preferring the bottom of these bodies of water.
