Acanthomorpha
- "Acanthomorpha" is also a name for a proposed clade of spiny-rayed Teleostei. It unites the superorders Acanthopterygii, Paracanthopterygii, the doubtfully distinct Polymyxiomorpha and perhaps the disputed Lampridiomorpha and Scopelomorpha.

Acanthomorpha (meaning "thorn-shaped" in Greek) is an order of prehistoric fish that was described by Rosen in 1973. Fossils range from the Late Cretaceous to the Early Oligocene (99.6mya)-28.4mya). Older fossils (as recent as 70.6mya) occur in Alberta and Saskatchewan, Canada, and the late Palaeorhynchus zitteli occurs in Romania.[1] Late Cretaceous
