Heteropneustes is a genus of , the airsac catfishes, native to Asia. This genus is monotypic in the family Heteropneustidae.
Their bodies are elongated and compressed with greatly depressed heads. They have long air sacs that serve as lungs that extend from the gill chamber. Their dorsal fins are short and have no spine. Their pectoral fins have an associated venom gland, so the fish are considered dangerous. They are oviparity; distinct pairing is possible.
FishBase does not list H. fuscus while the Catalog of Fishes considers H. microps a synonym of H. fossilis.
