Kostas is Greek in Origin.

Rooted in Greek, Kostas (Κώστας) is the familiar short form of Konstantinos, itself from Latin Constantinus, derived from constans, “steadfast, firm.” The prestige of Emperor Constantine the Great and later Byzantine and Orthodox saints carried the name across the Greek-speaking world, where Kostas became an everyday, affectionate call-name. It rose to particular prominence in Greece and Cyprus during the 20th century and remains a steady favorite, bridging formal tradition and colloquial warmth.

Variants and related forms include the formal Konstantinos/Constantinos and its English equivalent Constantine; alternative spellings Kostas and Costas appear in the diaspora. Common diminutives are Kostis and Dinos (Ntinos), with the vocative Kosta heard in address. The feminine counterpart is Konstantina (often Dina/Ntina). The core meaning - “constant, reliable, resolute” - gives the name a virtue flavor, echoed by notable bearers such as poet Kostas Varnalis and sprinter Kostas Kenteris.
