The family Stromateidae or butterfish contains 15 species of ray-finned fish in three genera. Butterfishes live in coastal waters off the Americas, western Africa and in the Indo-Pacific.

The endemic New Zealand species Odax pullus is commonly called butterfish, but is from a separate family Odacidae. The Japanese butterfish Psenopsis anomala is from the separate family Centrolophidae. The African butter catfish is also known as the butter fish. In South Australia, the Argyrosomus japonicus is commonly called butterfish as well.
