'''Acanthuriformes''' is a large, diverse order of mostly marine ray-finned fishes, part of the Percomorpha clade. In the past, members of this clade were placed in the suborders Acanthuroidea and Percoidea of the order Perciformes, but this treatment is now considered paraphyletic.

This order contains many of the iconic tropical reef fish groups, such as surgeonfish, marine angelfish, butterflyfish, rabbitfish, grunts, and snappers. It also contains widespread, economically important food and sport fishes, such as drums, temperate basses, and porgies.<ref name=":1">{{Cite web |last=Fricke |first=R. |last2=Eschmeyer |first2=W.

== Etymology == The name comes from Ancient Greek ἄκανθα (''ákantha''), meaning "spine", οὐρά (''ourá''), and Latin ''formes'', meaning "form".

Some authors also lump the Lophiiformes and Tetraodontiformes within this group as the suborders Lophioidei and Tetraodontoidei, because Acanthuriformes is otherwise paraphyletic. However, they are presently retained as distinct orders by taxonomic authorities.<ref name="Near2024">{{Cite journal |last=Near |first=Thomas J. |last2=Thacker |first2=Christine E. |date=2024-04-18 |title=Phylogenetic Classification of Living and Fossil Ray-Finned Fishes (Actinopterygii) |url=https://bioone.org/journals/bulletin-of-the-peabody-museum-of-natural-history/volume-65/issue-1/014.065.0101/Phylogenetic-Classification-of-Living-and-Fossil-Ray-Finned-Fishes-Actinopterygii/10.3374/014.065.0101.full |journal=Bulletin of the Peabody Museum of Natural History |volume=65 |issue=1 |doi=10.3374/014.065.0101 |issn=0079-032X|url-access=subscription }}</ref>
