Peace is a comedy written and produced by the ancient Greek playwright Aristophanes. It first appeared in 421 BC and was awarded second prize for that year in Athens.

The elderly farmer Trygaeus is the central figure of the play. With Athens and Sparta fighting each other in the Peloponnesian War, Trygaeus mounts a giant beetle in the style of the hero Bellerophon mounting Pegasus and flies to heaven for an audience with Zeus, king of the gods. When Trygaeus arrives there, all the Olympian gods save Hermes have left heaven in the hands of War and his servant Havoc.

With the aid of members of the chorus (representing various Greek city-states), Trygaeus removes the stones while War and Havoc are gone from a cave imprisoning the statue of Peace and her companions Harvest and Festival. When she's released, however, Peace will only talk to Trygaeus and the other Greeks through Hermes. She is persuaded to return to Athens with the Greeks.

Trygaeus agrees to marry Harvest, and Festival is sent with another Greek to prepare a peace celebration. Arms merchants entering the town to sell the wares are offended by Trygaeus' sentiments and leave Athens in time for the wedding of Trygaeus and Harvest.
