Triportheidae, the hatchet characins, is a family of characiform fishes, including about 23 species. This family was raised from the status of a subfamily to family based on extensive analysis of characiform species. ^[2]

Fossils of this group date back to the Oligocene, with the fossil species † Lignobrycon ligniticus (Woodward, 1898) from Brazil. ^[3]
