Uzunada or Uzun ada (literally "long island") is an island situated at the entry of the Gulf of İzmir on the west coast of Turkey. It is situated between the Karaburun Peninsula, Turkey in the west, and the district of Foça in the east. Stretching over a length of c. 9 km in north-south direction, it is Turkey's fourth largest island, and its third largest in the Aegean Sea. It is also known under its Greek names of Makronisi ("long island") or Englezonisi ("Englishmen's island").[1] To its south are several smaller islets, including Yassıca.
"Uzunada" is also the name of several other, smaller islets along the Turkish Aegean coast.[1]
