The herring cale (Olisthops cyanomelas) is a species of ray-finned fish, a weed whiting from the family Odacidae which is endemic to Australia where it is found along the southern and southeastern coast.

It inhabits the surf zone, ranging to a depth of 30 m (98 ft) in rocky areas with plentiful growth of brown algae, which it feeds on.

This species grows to a length of 51 cm (20 in) SL.

[2] This species is the only known member of the genus Olisthops,[3] but it has frequently been placed in Odax instead.
