The orangeband surgeonfish is a surgeonfish (Acanthuridae) from the Indo-West Pacific. Adults are grey-brown with a conspicuous orange, blue-edged band behind the head; juveniles are bright yellow. It inhabits seaward reefs with bare rock or mixed rubble and sand, from nine to at least forty-six metres depth. It grazes algae and detritus from the bottom.
