Greek tragedy is one of the three principal theatrical genres from Ancient Greece and Greek inhabited Anatolia, along with comedy and the satyr play. It reached its most significant form in Athens in the 5th century BC, the works of which are sometimes called Attic tragedy.

Ancient Greek comedy was one of the final three principal dramatic forms in the theatre of classical Greece. Athenian comedy is conventionally divided into three periods: Old Comedy, Middle Comedy, and New Comedy. Old Comedy survives today largely in the form of the eleven surviving plays of Aristophanes; Middle Comedy is largely lost, i.e. preserved only in relatively short fragments by authors such as Athenaeus of Naucratis; and New Comedy is known primarily from the substantial papyrus fragments of Menander.
