Kokkina (Greek: Κόκκινα [locally [ˈkot͡ʃina]]; Turkish: Erenköy or Koççina) is a coastal exclave of the de facto Northern Cyprus, and a former Turkish Cypriot village and enclave in Cyprus. It is surrounded by mountainous territory, with the Morphou Bay on its northern flank. Kokkina sits several kilometres west of the Northern Cyprus mainland and is a place with symbolic significance to Turkish Cypriots, because of the events of August 1964 (cf. Battle of Tillyria). In 1976, all Kokkina inhabitants were transferred to Gialousa and the exclave has since functioned as a Turkish Army military camp.
The Tylliria/Dillirga region, where Kokkina is situated, had been a place of intense confrontation between the Greek Cypriot and Turkish Cypriot communities during the inter-communal struggle of 1963–1964. On 4 April 1964, armed groups originating from both communities had fought over a strategic location overlooking the region's only highway. There had also been several sporadic incidents of gunfire between villages of the region. On 8 April 1964, the United Nations Force in Cyprus (UNFICYP) managed to arrange a ceasefire which was enforced by stationing UNFICYP troops at several critical points.
