Tetraroge is a genus of ray-finned fishes, waspfishes belonging to the subfamily Tetraroginae, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives.

Tetraroge was first described as a genus in 1860 by the German born British herpetologist and ichthyologist Albert Günther.

In 1919 David Starr Jordan designated Apistus barbatus, which had been described by Georges Cuvier in 1829 from Java, as the type species of the genus.

The dorsal fin contains between 14 and 17 spines and has its origin to the front of the level of the rear margin of the orbit.

[7][8] They are found in estuaries and mangroves and penetrate freshwaters in rivers by as much as 40 km (25 mi) from the coast.
