Kyrillos is a unisex given name of Greek origin, derived from the Greek word 'kyrillos', which means 'lord' or 'master'. It gained popularity in the Middle East and Egypt due to its association with Saint Kyrillos I, the Patriarch of Alexandria during the 11th century. The name has also been used among Coptic Christians as a traditional given name for centuries. In the West, however, it is less commonly used and may be more familiar in its alternative spellings like Kirillos or Kyrillios.
"Kyrillos experienced varied popularity over the years, with a notable peak in 2013 (20 births) and a significant drop in recent years (6 births in both 2020 and 2023)."
