Redigobius is a genus of fish in the goby family, Gobiidae, known commonly as dualspot gobies. They are native to the western Indo-Pacific region, where they occur in estuaries and freshwater habitats just above the tidal influence.
Some of these gobies are abundant fish species. The most widespread is the speckled goby (R. bikolanus), which occurs throughout the western Pacific Ocean and from Australia to Africa. Some Redigobius are kept as aquarium pets. The Fijian endemic Lever's goby (R. leveri) is featured on the ten-dollar bill in the 2013 series of Fijian currency.
