Paracanthopterygii is a superorder of fishes. Members of this group are called paracanthopterygians.

The oldest members are known as fossils from the Cenomanian. ^[1]

It includes four orders: ^{[2] [3]}

• †Sphenocephaliformes
• Percopsiformes (trout-perches & allies)
• Zeiformes (dories)
• Gadiformes (cods & allies, including Stylephoriformes) ^[4]

The indeterminate fossil marine paracanthopterygian † Trebiciania Sorbini & Bannikov, 1996, the only member of the family Trebicianiidae, is known from the Early Paleocene of Italy. ^[5]
