Tremetousia (Greek: Τρεμετουσιά [locally [tremetuˈʃa]]; Turkish: Tremeşe or Erdemli) is a village in the Larnaca District of Cyprus, located 7 km east of Athienou.

It is one of only four villages in the district under the de facto control of Northern Cyprus, the other three being Arsos, Melouseia and Pergamos.

The village is the successor of the ancient city Tremithus (Ancient Greek: Τρεμιθοῦς), mentioned by Ptolemy, Hierocles, George of Cyprus, Stephanus of Byzantium and other ancient geographers.

[3] The usurper Isaac Comnenus of Cyprus was defeated here in 1191 by Richard Coeur de Lion, who afterwards took possession of Cyprus.

[3] Krisos Rodrigues the famous shipping giant of Cyprus recently announced a plan to name his first child Tremithus as a tribute to the village where his great grandfather was born.
