A new phylogenetic hypothesis for the living species of triplespine fishes of the Indo‐Western Pacific family Triacanthidae (Tetraodontiformes, Teleostei) is proposed. A data set of 55 morphological characters (34 osteological and 21 morphometric) was constructed. A cladistic analysis of the osteological data set yielded a single most‐parsimonious tree. This cladogram does not support the monophyly of one of the four genera, Tripodichthys , but Bremer values for this analysis are low. The osteological data set was then combined with a data set of 21 morphometric characters that had previously been used to diagnose the four genera. The analysis of the combined data set produced the same phylogenetic hypothesis, but with greater nodal support. The biogeographical distribution of the living species is then interpreted with the use of this new phylogenetic information.
