Gobiodon histrio, the Broad-barred goby, is a species of goby native to the Indian Ocean from the Red Sea to the western Pacific Ocean to southern Japan, Samoa and the Great Barrier Reef. This species is a reef dweller, being found at depths of from 2 to 15 metres (6.6 to 49.2 ft). It can reach a length of 3.5 centimetres (1.4 in) TL.
