"Astronotus" is a genus of fish from the family Cichlidae. The genus is one of three genera which make up the tribe Chaetobranchini. There are two species in the genus (listed below) both of which are found in the Amazon River basin of South America. "Astronotus" species grow to 35 cm in size, and are monomorphic. They are opportunistic omnivores and consume a range of smaller fish, crustaceans, mollusks and other invertebrates in the wild.

One species, "Astronotus ocellatus", is popular in the aquarium trade where it goes under the trade name of the "Oscar". "A. ocellatus" forms monogamous pairs which spawn in the open, typically on a flattened stone or in a shallow depression. The juvenile colouration is different from that of the adult and may aid in camouflage of the fry.

In contrast, "A. crassipinnis" is rarely exported and is not seen often in the aquarium trade.
