'''Acropomatidae''' is a family of ray-finned fish in the order Acropomatiformes, commonly known as '''lanternbellies'''. ''Acropoma'' species are notable for having light-emitting organs along their undersides. They are found in all temperate and tropical oceans, usually at depths of several hundred meters.<ref name="Fishbase">{{FishBase family|family=Acropomatidae|month=December|year=2019}}</ref> There are about 32 species in as many as 9 genera, although some authorities recognise fewer genera than Fishbase does.

Members of the family are generally small, with some ranging up to 40 cm, but most no more than 15 cm. They have two dorsal fins, the first with seven to 10 spines and the second with possibly a spine in addition to eight to 10 soft rays. The anal fin has two or three spines, and the pelvic fins one spine and five soft rays.
