Strofades or Strofadia (Greek: Στροφάδες or Στροφάδια) is a group of two small Greek islands in the Ionian Islands. They lie about 44 km (27 mi) south-southeast of the island of Zakynthos. Administratively they are part of the Municipality of Zakynthos. The larger island, Stamfani, has an old fortress/monastery built in 1241. The smaller is Arpia. Both are sparsely vegetated and rocky. There is a strong avian presence on the islands, and hunting is prohibited. Species include Cory's shearwater (Calonectris diomedea) and migratory passerines. There is also a large spring migration of turtle doves (Streptopelia turtur).
According to legend, the islands' name, meaning "Islands of Turning," refers to Zetes and Calaïs, sons of Boreas, who voyaged with the Argonauts. Zetes and Calaïs rescued Phineus from the Harpies. They succeeded in driving the monsters away but did not kill them, as a request from the goddess of the rainbow, Iris, who promised that Phineas would not be bothered by the Harpies again. They were turned back at the Strophades by Iris while continuing their pursuit of the creatures.
