Acanthopagrus latus, the yellowfin seabream, grey bream, Houttuyn's yellowfin seabream, Japanese bream or yellow-finned black porgy, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. This fish is found in the Western Pacific Ocean.

Taxonomy Acanthopagrus latus was first formally described in 1782 by the Dutch naturalist Martinus Houttuyn with its type locality given as Hirado Bay near Nagasaki in Japan. This species was thought to have a widespread Indo-Pacific range but has now been divided into separate species, A. longispinnis in the Bay of Bengal, A. morrisoni off north-western Australia, A. arabicus in the Persian Gulf and the Arabian Sea and A. sheim in the Persian Gulf and northern Gulf of Oman, with A. latus sensu stricto in the Western Pacific. Some authorities classify the genus Acanthopagrus in the subfamily Sparinae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.

Etymology Acanthopagrus latus has the specific name latus, meaning "broad", Houttuyn described this species as being the widest species in the genus he placed it in Sparus.

Description Acanthopagrus latus has 10 spines and 10 or 11 soft rays supporting the dorsal fin and 3 spines and 8 or 9 soft rays supporting the anal fin. It has a deep body which has a standard length which is twice its depth. The dorsal profile of the head has a noticeable bulge at the eyes. The overall colour is light grey to whitish, darker on the upperbody and typically being yellowish on the abdomen.
