Rhabdosargus thorpei, the bigeye stumpnose, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies.

Rhabdosargus thorpei was first formally described in 1979 by the South African ichthyologist Margaret Mary Smith with its type locality given as Mabibi in KwaZulu-Natal.

[3] Rhabdosargus thorpei belongs to the genus Rhabdosargus, a name which is a refixes rhabdos, meaning "stick" or "rod", an allusion to the yellow abdominal band of Sargus auriventris, its type species, to Sargos, a name used for Sparid fish in ancient Greek at least as long ago as Aristotle but in this case is a reference to Sargus as a synonym of Diplodus.

[1] Rhabdosargus thorpei is endemic to the southwestern Indian Ocean where it is found along the southeastern African coast between the Eastern Cape and southern Mozambique, possible as far north as Xai-Xai, off Europa Island in the Mozambique Channel and around southern Madagascar.

[1] The bigeye stumpnose is mainly taken in inshore waters in the surf zone and where there are shallow rocky and coral reefs.
