Meaning & origin

Kostantinos is a Greek masculine name, a modern romanization of Konstantinos, the Greek form of Constantine. Its earliest recorded use in the United States is 1970, and it reached its peak popularity in 1974, remaining stable in usage since then. With no appearances in the top 1000, it is a very rare name in the US, but it is common in Greece and among Greek diaspora communities. The name carries the legacy of Byzantine emperors and Saint Constantine, giving it a historical and religious significance. Parents choosing Kostantinos often honor Greek heritage or family traditions. Despite its rarity, the name has a strong, classic feel with the familiar nickname Kostas.

Kostantinos is a modern romanization of the Greek name Κωνσταντίνος (Konstantinos), which derives from the Latin name Constantinus, itself from constans (constant, steadfast). The name was borne by several Roman and Byzantine emperors, notably Constantine the Great, the first Christian emperor. In Greece, it has remained a staple name, often given in honor of Saint Constantine.
