Meaning & origin

Cirilo, a name with deep ecclesiastical roots, has never been common in the United States. It first appeared in U.S. records in 1915 and saw its peak usage in 1927, though even then it remained a rare choice. With a current 2025 rank of 10,695 and a rate of about 1 in 284,679, Cirilo has maintained a stable but sparse presence. The name is most often associated with Spanish- and Portuguese-speaking communities, reflecting its derivation from the Greek Kyrillos via Latin. While it has not seen a revival in recent decades, its classic sound and religious heritage give it a quiet, enduring appeal for families seeking a distinctive name with historical depth.

Cirilo is the Spanish and Portuguese form of the Greek name Kyrillos, itself derived from kyrios meaning 'lord' or 'master.' The name was borne by several early saints, most notably Saint Cyril of Alexandria, a prominent theologian of the 5th century, and Saint Cyril, who with his brother Methodius evangelized the Slavic peoples. The name spread throughout the Christian world, particularly in Eastern and Southern Europe, and was brought to the Americas by Spanish and Portuguese settlers.
