Gerres is a genus of mojarras found mostly in coastal regions from the eastern Atlantic Ocean through the Indian Ocean to the western Pacific.

A single species, G. simillimus, is from the East Pacific.

At least one species, Gerres cinereus (yellowfin mojarra), displays an ability akin to gyroscopic stability, allowing it to remain in a remarkably static spatial position relative to the water flowing around it.
