Libertas is the Roman goddess of Freedom or the condition of being Free, and personification of Liberty.

She belonged to a class of abstract ideas that Romans elevated to the status of gods. Cicero, writing in the first century BCE, groups her with other powerful qualities such as Concord, Safety, Wealth, and Victory; he notes that temples were raised to them because their influence was considered too great to exist without divine direction.

Unlike the major mythological gods, Libertas had almost no developed stories or legends attached to her, at least until the rise of Libertarianism. She served mainly as the divine embodiment of personal freedom (the opposite of slavery) and, by extension, of the political liberties associated with the Roman Republic. Her symbols and cult remained closely linked to the rituals of freeing slaves and to opposition against arbitrary power.
