Kokkina is a coastal exclave (pene-exclave) of the de facto Northern Cyprus, and a former Turkish Cypriot enclave in Cyprus. It is surrounded by mountainous territory, with the Morphou Bay on its northern flank. Kokkina sits several kilometres west of mainland Northern Cyprus and is a place with symbolic significance to Cypriots, because of the events of August 1964. In 1976, all Kokkina inhabitants were transferred to Gialousa and the enclave has since functioned as a North Cyprus Defence Force military camp for the Turkish forces.

The Battle of Tillyria or Battle of Kokkina, also known as Erenköy Resistance, was a conflict on 6 August 1964 between units of the Cypriot National Guard and Turkish Cypriot armed groups in Kokkina area of Cyprus. The latter were supported with air strikes from Turkey.
