The blue weed whiting (Haletta semifasciata) is a species of ray-finned fish, a weed whiting from the family Labridae, which is endemic to Australia where it is only found along the southern coast. It is found in brackish and marine waters in sheltered locations at depths of from 1 to 7 metres (3.3 to 23.0 ft). This species inhabits areas with a substrate of sand with beds of seagrass where it feeds on small invertebrates and algae and the seagrasses themselves.
