Ayvalık is a seaside town on the northwestern Aegean coast of Turkey. It is a district of Balıkesir province. The town centre is connected to Cunda Island by a causeway and is surrounded by the archipelago of Ayvalık Islands, which face the nearby Greek island of Lesbos
Ayvalık was an ancient Aeolian Greek port-town, called Kydonies. Its name was changed to Ayvalık in the Ottoman era. Before 1923 the town was predominantly Greek, and although the Turks used its Turkish name, the Greeks used both the old name Kydonies and the new one Hellenised to Aivali. The Greeks knew Cunda Island as Moschonisia while the Turks called it Alibey Island.
