Kiryllo is Greek in Origin.

Kiryllo is an East Slavic form of the Greek name Kyrillos (Κύριλλος), derived from kyrios, meaning “lord, master,” hence “lordly” or “belonging to the Lord.” The spelling Kiryllo reflects a hybrid transliteration: the double l echoes Russian Kirill (Кирилл), while the final -o mirrors Ukrainian Kyrylo (Кирило) and South Slavic Kirilo. In Church Slavonic and Byzantine ecclesiastical usage, the name circulated widely, reinforcing its prestige in Orthodox cultures.

Use spread through veneration of major saints: Cyril of Jerusalem, Cyril of Alexandria, and the 9th‑century missionary Saint Cyril (of Cyril and Methodius), credited with the Glagolitic script and the Christianization of the Slavs. Today it appears across Eastern Europe, with modern revivals in Ukraine, Russia, and Belarus. Variants include Cyril, Cyrillus, Kyrillos, Kirill, Kyrylo, Kiryl, Kiril/Kirilo, Cyrille, Cirilo, and Cirillo. Common diminutives are Kir, Kiryusha (Russian), and Kyryk (Ukrainian).
