This study reports the presence of three alien molluscs from Iskenderun Bay (SE Turkey). Amathina tricarinata (Linnaeus, 1767) and Petricola hemprichi Issel, 1869 have prior records from other regions of Mediterranean, but, Cardites akabana (Sturany, 1899) first recorded in this paper. Since all of them are present in the Red Sea or Suez Canal, they can be considered as Lessepsian immigrants.
