Prometheus Bound is an ancient Greek tragedy traditionally attributed to Aeschylus and thought to have been composed sometime between 479 BC and the terminus ante quem of 424 BC. The tragedy is based on the myth of Prometheus, a Titan who defies Zeus, and protects and gives fire to mankind, for which he is subjected to the wrath of Zeus and punished.

Aeschylus was an ancient Greek tragedian often described as the father of tragedy. Academic knowledge of the genre begins with his work, and understanding of earlier Greek tragedy is largely based on inferences made from reading his surviving plays. According to Aristotle, he expanded the number of characters in the theatre and allowed conflict among them. Formerly, characters interacted only with the chorus.
