Arete of Cyrene (Greek: Ἀρήτη; fl. 5th–4th century BC) was a Cyrenaic philosopher, and the daughter of Aristippus of Cyrene.She learned philosophy from her father, Aristippus, who had himself learned philosophy from Socrates. Arete, in turn, taught philosophy to her son - Aristippus the Younger - hence her son was nicknamed "Mother-taught" (Greek: μητροδίδακτος).
