Acrossocheilus is a genus of ray-finned fishes in the family Cyprinidae, native to freshwater in China, Taiwan, Laos, and Vietnam. They are fairly small, no more than 30 cm (1 ft) in standard length. There are currently 26 recognized species of this genus. Four species have sometimes been moved to Masticbarbus, but it has yet to be widely accepted. Some species from Southeast Asia have been moved to Neolissochilus.
