Rhabdosargus sarba, also known as the goldlined seabream, silver bream, tarwhine, or yellowfin bream, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This fish has a wide Indo-Pacific distribution.

Taxonomy Rhabdosargus sarba was first formally described as Sparus sarba in 1789 by the German zoologist Johann Friedrich Gmelin from notes written by Peter Forsskål. The type locality was given as Jeddah. In 1855 Wilhelm Peters described a new species Sargus auriventris from Mozambique, in 1933 Henry Weed Fowler classified S. auriventris in the new monospecific genus Rhabdosargus. designating it as its type species. S. auriventris is considered to be a junior synonyms of Gmelin's Sparus sarba. The genus Rhabdosargus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World. Some authorities classify this genus in the subfamily Sparinae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.

Etymology Rhabdosargus sarba 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.
