Elaiussa Sebaste or Elaeousa Sebaste (Greek: Ελαιούσα Σεβαστή) was an ancient Roman town located 55 km (34 mi) from Mersin in the direction of Silifke in Cilicia on the southern coast of Anatolia (in modern-day Turkey). Elaiussa, meaning olive, was founded in the 2nd century B.C. on a tiny island attached to the mainland by a narrow isthmus in Mediterranean Sea.
