The Stephanoberyciformes are an order of marine ray-finned fishes, consisting of about 45 species, the majority (37) of which belong to the ridgehead family (Melamphaidae). The Stephanoberyciformes are mostly uncommon deep-sea types with little if any importance to commercial fishery. They share many morphological similarities with the Beryciformes, their sister order.
Common characteristics include a generally rounded body, a toothless palate, rather thin skull bones, and a missing orbitosphenoid bone (except for Hispidoberyx).
J.S. Nelson classifies the whalefishes (Cetomimiformes) as a superfamily Cetomimoidea of this order.
