The bay whiting (Sillago ingenue) is a species of coastal marine fish of the smelt-whiting family, Sillaginidae.

The bay whiting's range extends throughout the west Indian Ocean, including northern Australia, Thailand, India and Taiwan, where it inhabits protected waters.

Bay whiting are an important part of some inshore fisheries around Australia and Asia, where subsistence and commercial fishermen regularly take the species.

[3] The species was first identified and named Sillago ingenuua by Roland McKay in his comprehensive 1985 review of the family Sillaginidae, with the holotype collected near Chantaburi, in the Gulf of Thailand in 1975.

[2] The bay whiting has a pale sandy brown head and body, ranging to a light fawn with no obvious mid-lateral silvery band as in S. argentifasciata.

[6] The diet of bay whiting has been the focus of a study investigating trophic relations between this species, Sillago sihama, and other similarly distributed fish of the South China Sea.

[7] Unlike other species of sillaginid,[8] the bay whiting doesn't have a large dietary shift as it moves to adulthood, causing parents to compete with offspring to an extent.
