Otocephala is a clade of ray-finned fishes within the infraclass Teleostei which evolved some 230 million years ago. It is named for the presence of a hearing (otophysic) link from the swimbladder to the inner ear. Other names proposed for the group include Ostarioclupeomorpha and Otomorpha.
The clade contains Clupeiformes (herrings) and Ostariophysi, a group of other orders including Cypriniformes (minnows and allies), Gymnotiformes (knifefish), and Siluriformes (catfish). Otocephala may also contain Alepocephaliformes (slickheads), but as yet (2016) without morphological evidence.
