Mugiliformes is a small order of percomorph fish in the clade Ovalentaria. [1] [2]
This order is recognized by the Catalog of Fishes (2025). It contains only two families: [3] [4]
 
 Until recently, this order was restricted to only the mullets, but phylogenetic studies support the Asiatic glassfishes (previously placed as incertae sedis within the Ovalentaria) [6] being their closest relatives. The order is thought to be the sister group to the Blenniiformes. Other authors instead treat this order as a clade within an expanded Blenniiformes, and also find the Congrogadidae to be allied with the mullet-glassfish clade. [7]
