Apogon is a large genus of fish in the family Apogonidae, the cardinalfishes. They are among the most common fish on coral reefs. Over 200 species have been classified in genus Apogon as members of several subgenera. Some of these subgenera, such as Ostorhinchus, have been elevated to genus status, leaving just over 50 species in the genus.

Gymnapogon is a genus of fish in the family Apogonidae. They are native to the Indo-West Pacific and central Pacific Oceans, where they occur in reefs and nearby habitat types. These species are usually no more than 5 centimeters long and have semitransparent bodies without scales. The genus name is a compound noun formed by combining the Greek gymnos meaning "naked", referring to the lack of scales in the type species, Gymnapogon japonicus, and Apogon, the type genus of the Apogonidae. One species, the B-spot cardinalfish, is notable for its larvae being rather large, conspicuous and fast-swimming.
