The following families are classified within this order, based on Catalog of Fishes (2025):4
*Nota bene: Although traditionally considered its own family Scaridae, parrotfish have more recently been found deeply nested within the wrasse family Labridae by molecular phylogenetics, such that parrotfish are instead classified in the tribe Scarini.5
