Ayvalık Islands (Turkish: Ayvalık Adaları, Latin: Hecatonnesi, Ancient Greek: Ἑκατόννησοι, romanized: Hekatonesoi), are the group of islands around Ayvalık district of Turkey in Balıkesir Province in the Northeastern Aegean Sea. There are 22 islands and numerous rocks in the group, with Cunda Island, now a peninsula, being the largest. People live only on Cunda and Lale Islands. Cunda and Lale islands are linked to Ayvalık on the mainland, by a causeway enabling transportation by car. Cunda also has a ferry link from the main town, Alibey, to Ayvalık during the summer.
A Greek Orthodox metropolis was established, based in Cunda island, for some months in 1922.
