Paralabrax is a genus of fishes in the family Serranidae. They are known commonly as rock basses. The nine species in the genus are native to rocky reef habitat in the eastern Pacific and western Atlantic Oceans, where they are often dominant predators in the ecosystem. They are also commercially important in local fisheries.

Like many fish in the family Serranidae, some Paralabrax species are hermaphrodites, specifically protogynous hermaphrodites, which are female when young and eventually change into males. Others are gonochores, with individuals being either male or female and never changing sex. Gonochores in this genus are thought to be "secondary gonochores", species with ancestors that were hermaphrodites and lost the ability to change sex. An exception is the barred sand bass (P. nebulifer), which is a gonochore which has retained the ability. In addition, the spotted sand bass (P. maculatofasciatus) appears to be flexible, with some populations made up of gonochores and some made up of hermaphroditic individuals.

Paralabrax species generally spawn early in summer, their larvae joining the ichthyoplankton when the water is warmest.

Several species are of economic importance as food fish. The spotted sand bass (P. maculatofasciatus) is harvested in the commercial fishing industry and is caught for subsistence.

Some of these fish are also popular catches in recreational fishing. The kelp bass (P. clathratus) and barred sand bass (P. nebulifer) are sought after in the waters along the coast of Southern California and northern Baja California, where they have both been in the top three species caught on commercial sportfishing tours.
