List of marine bony fishes of South Africa

List ordering and taxonomy complies where possible with the current usage in World Register of Marine Species (WoRMS), and may differ from the cited source, as listed citations are primarily for range or existence of records for the region.

Sub-taxa within any given taxon are arranged alphabetically as a general rule.

Osteichthyes (/ˌɒstiːˈɪkθiːz/ ost-ee-IK-theez; from Ancient Greek ὀστέον (ostéon) 'bone' and ἰχθύς (ikhthús) 'fish'), also known as osteichthyans or commonly referred to as the bony fish, is a diverse superclass of vertebrate animals that have endoskeletons primarily composed of bone tissue.

They can be contrasted with the Chondrichthyes (cartilaginous fish) and the extinct placoderms and acanthodians, which have endoskeletons primarily composed of cartilage.

The vast majority of extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 orders, over 435 families and 28,000 species.
