Belligobio is a small genus of freshwater ray-finned fish belonging to the family Gobionidae, the gudgeons.

[1] The fishes in this genus are found in China and Japan.

The type species of Belligobio is Belligobio eristigma, a taxon which has been regarded as a synonym of Hemibarbus mylodon, a species not currently classified in Belligobio and some authorities suggest that Belligobio is a sub-genus within Hemibarbus.

[2] However, Eschmeyer's Catalog of Fishes, recognises B. eristigma as a separate valid species.
