Aonyx is a genus of otters, containing three species, the African clawless otter, the Congo clawless otter, and the Asian small-clawed otter. The word aonyx means "clawless", derived from the prefix a- ("without") and onyx ("claw/hoof").

Zoologists differ as to whether or not to include the Asian small-clawed otter in this genus, or in its own genus Amblonyx.[3][4] They also differ as to whether the Congo clawless otter is a species, or is conspecific with the African clawless otter.[5][6][7][8][9]
