Classical mythology, also known as Greco-Roman mythology or Greek and Roman mythology, is the collective body and study of myths from the ancient Greeks and ancient Romans. Mythology, along with philosophy and political thought, is one of the major survivals of classical antiquity throughout later Western culture. The Greek word mythos refers to the spoken word or speech, but it also denotes a tale, story or narrative.

Myth is a genre of folklore or theology consisting primarily of narratives that play a fundamental role in a society, such as foundational tales or origin myths. For scholars, this is very different from the vernacular usage of the term "myth" that simply refers to something that is not true. Instead, the truth value of a myth is not a defining criterion.
