Crito ( or ; ) is a dialogue by the ancient Greek philosopher Plato. It is a conversation between Socrates and his wealthy friend Crito regarding justice (δικαιοσύνη), injustice (ἀδικία), and the appropriate response to injustice. Socrates thinks that injustice may not be answered with injustice, and refuses Crito's offer to finance his escape from prison. This dialogue contains an ancient statement of the social contract theory of government.
