The olive rockfish, Acanthoclinus fuscus, is a longfin of the family Plesiopidae, found only in New Zealand's intertidal zone and in rock pools at low tide. Their length is up to 30 cm.

The olive rockfish is a resident intertidal species with homing behavior, found in pools with rocks or boulders. It may leave tide pools if aquatic conditions become inhospitable. It feeds mostly on invertebrates, particularly crustaceans and molluscs. It is able to breathe air when out of water, and swims with an eel-like motion.
