From Old Persian 'Kurush,' possibly meaning 'sun' or 'far-sighted,' borne by Cyrus the Great of Persia.
Cyrus comes into English through Greek Kyros and Latin Cyrus, ultimately from the Old Persian royal name Kuruš. Its exact original meaning is debated, which is common with very ancient names, though traditional interpretations have linked it to ideas such as the sun, youth, or authority. What is certain is the name’s remarkable antiquity and prestige: Cyrus is one of the great surviving names of the ancient Near East, preserved across Persian, Greek, biblical, and later European traditions.
Its central historical bearer is Cyrus the Great, founder of the Achaemenid Persian Empire in the 6th century BCE. He became famous not only as a conqueror but also as a ruler remembered for statecraft and relative tolerance, especially in Jewish tradition, where he is honored for allowing the exiled Jews to return to Jerusalem. That biblical connection helped keep the name alive in Christian usage, particularly among Protestants who favored dignified Old Testament names.
In modern times Cyrus has carried both grandeur and a faintly intellectual, antique sheen. It appears in literature, religious history, and popular culture, from saints and scholars to figures in entertainment. Because it is both ancient and sharply simple, Cyrus has a rare quality: it feels old-world and imperial, yet still clean and modern to the contemporary ear.
