Tripodichthys is a genus of marine ray-finned fish belonging to the family Triacanthidae, the triplespines or tripodfishes.

Tripoichthys was first proposed as a genus in 1968 by the American ichthyologist James C. Tyler with Triacanthus blochii designatedas its type species.[1]T.

The specific name of the type species honours Marcus Elieser Bloch, the describer of Triacanthus biaculeatus which was thought to be a congeneric with T. blochii.

The specific name of T. angustifrons means "narrow forehead" and refers to this species thinner snout than Triacanthus brevirostris, its assumed congener.

In T. oxycephalus the pelvis is wide between bases of the pelvic fin spines and the caudal peduncle is short.
