Syca or Syce or Syke (), also called Sycae or Sykai (ãàúñï), possibly also called Setos, was a town of ancient Cilicia and later of Isauria, between Arsinoë and Celenderis. It became a bishopric; no longer the seat of a residential bishop, it remains a titular see of the Roman Catholic Church.
Syce is located near Softa Kalesi in Asiatic Turkey.
