Carassius is a genus in the ray-finned fish family Cyprinidae. Most species in this genus are commonly known as crucian carps, though this term often specifically refers to C. carassius. The most well known is the goldfish (C. auratus). They have a Eurasian distribution, apparently originating further to the west than the typical carps (Cyprinus), which include the common carp (C. carpio).

Species of Carassius are not particularly close relatives of the typical carps of Cyprinus, but rather form a more basal lineage of the subfamily Cyprininae.^[1]
