In Greek mythology, Adrasteia (/ˌædrəˈstiːə/; Greek: Ἀδράστεια (Ionic Greek: Ἀδρήστεια), "inescapable"; also spelled Adrastia, Adrastea, Adrestea, Adastreia) was a nymph who was charged by Rhea with nurturing the infant Zeus , in secret in the Dictaean cave, to protect him from his father Cronus (Krónos).
- She is known to have been worshipped in hellenised Phrygia (north-western Turkey), probably derived from a local Anatolian mountain deity. She is known from inscriptions in Greece from around 400 BC as a deity who defends the righteous.
- Adrastea may be interchangeable with Cybele a goddess associated with childbirth. The Greeks cultivated a patronic system of gods who served specific human needs, conditions or desires to whom one would give praise or tribute for success in certain arenas such as childbirth.
