List of marine spiny-finned fishes of South Africa

This is a sub-list of the List of marine bony fishes of South Africa for spiny-finned fishes recorded from the oceans bordering South Africa.

List ordering and taxonomy complies where possible with the current usage in Wikispecies and may differ from the cited source, as listed citations are primarily for range or existence of records for the region.

Acanthopterygii (meaning "spiny-finned one") is a superorder of bony fishes in the class Actinopterygii.

Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole.

The suborder includes the berycids and their allies, but by far the largest member of the group is the Percomorpha, the most diverse vertebrate clade.
