Deneia (Greek: Δένεια [locally [ˈðeɲˑa]]; Turkish: Denya) is a village in the Nicosia District of Cyprus, west of Mammari.

It is one of only four villages located within the United Nations Buffer Zone, the other three being Pyla, Athienou and Troulloi.

The Turkish Cypriots of the village fled to secure Turkish Cypriot enclaves in Fotta, Krini, Ortaköy and Lefka in 1964, in the wake of intercommunal violence.

During the Turkish invasion of Cyprus in 1974, Greek Cypriot inhabitants also fled the village as the Turkish army advanced to the village, but they returned after the army withdrew.

Turkish Cypriot inhabitants were relocated to Şirinevler (Agios Ermolaos), where they were given land.
