Kalopsida (Greek: Καλοψίδα; Turkish: Çayönü) is a village in the Famagusta District of Cyprus, 8 kilometres (5.0 mi) east of Lysi.

Before 1974, Kalopsida was an exclusively Greek Cypriot village; its residents were displaced during the Turkish invasion of Cyprus.

Presently, it is inhabited by displaced Turkish Cypriots from the south and some families from Turkey.

[3] Kalopsidiotes (pronounced [kalopsiˈθcotes]; residents of Kalopsida) were known for being very brave and constantly carrying knives, which they regarded as a symbol of pride.
