Yialousa (Greek: Γιαλούσα [from Αιγιαλούσα, meaning " Sea"]; Turkish: Yeni Erenköy) is a town in Cyprus, located on the Karpas Peninsula. Situated de jure in the Famagusta District of the Republic of Cyprus, Yialousa is under the de facto control of Northern Cyprus, serving as a sub-district in the İskele District. In 2011, Yialousa had a population of 1,774.
In 1960, Yialousa had 2,538 inhabitants, only one of whom was a Turkish Cypriot, the rest being Greek Cypriot. By 1973, the population was 2,460, and composed of only Greek Cypriots. When the Turkish and Turkish Cypriot forces reached the town during the Turkish invasion of Cyprus in August 1974, the Greek inhabitants could not move to the south of the island, which was controlled by the Republic of Cyprus. Residents of the village were forcibly evicted by the Turkish army, whilst some left the village gradually because of restrictions on freedom of movement and education, and to reunite with family members who had been taken as prisoners and had ended up in the southern portion of the island after they were returned. In 1976, displaced Turkish Cypriots from the Kokkina exclave (Turkish Erenköy) were resettled in the village, and it was renamed "Yeni Erenköy" ("New Erenköy").
