Archosargus is a genus of marine ray-finned fishes belonging to the family Sparidae, the sea breams and porgies.

Archosargus was first proposed as a monospecific genus in 1865 by the American biologist Theodore Gill with Sparus probatocephalus as its only species.

[1] S. probatocephalus had originally been formally described in 1792 by the German naturalist Johann Julius Walbaum with its type locality not given but it is thought to be New York.

[2] The genus Archosargus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World.

[3] Archosargus combines archon, meaning “ruler”, and sagrus, a Greek name for seabreams dating as far back as Aristotle, although in this case Gill was probably referencing Sargus, a synonym of Diplodus.
