The Dionysades (Greek: Διονυσάδες, also Γιανυσάδες - Gianysades) is a small group of islands off Sitia on the northeast coast of Crete. The group includes the islands Gianysada, Dragonada, Paximada, and Paximadaki. Administratively this group comes within the Sitia municipality in Lasithi.
These islands were once a place of worship of the ancient Greek god Dionysus. Archaeologists have found artefacts, from ancient and early Christian eras, indicating that the islands may have been inhabited in the past.
