Trachiniformes is an order of percomorph bony fish, whose contents are traditionally placed in suborder Trachinoidei of Perciformes.

However, Trachiniformes is recovered as polyphyletic in recent large scale molecular phylogenetic studies. Trachinidae itself is recovered as part of Percoidei, while other families respectively belong to Scombriformes, Gobiiformes, new orders Uranoscopiformes and Pempheriformes, and other clades in Perciformes.

The following families make up the Trachiniformes: (with respectively belonging taxa following the molecular phylogenies)
