In Roman mythology, Discordia is the Roman equivalent of the Greek Eris, goddess of strife and discord. She was the daughter of Nox (Night) and Erebus. Unlike her opposite Concordia, Discordia was not a cult goddess, but simply a literary personification.
Like Eris, Discordia has no mythology other than her involvement in the Judgement of Paris, and was especially associated with the strife and discord in war. She was, in particular, associated with Roman civil war.
