Meaning & origin

Kylian is a modern name that first appeared in U.S. birth records in 2005. It has seen a steady rise since 2010, reaching its peak rank of 622 in 2023, with a 1-in-3,813 rate in the most recent data (2025). The name is most popular in states like Connecticut, Florida, and North Carolina. As a contemporary spelling variation of the Irish name Kilian or Cillian, Kylian reflects a broader trend of respelling traditional names to create distinctive yet familiar-sounding options. Its trajectory upward suggests growing appeal among parents seeking a modern name with a soft, European flair.

Kylian is a modern respelling of Kilian or Cillian, names with Irish and Gaelic roots. Kilian derives from the Irish name Cillian, which may come from 'ceallach' meaning 'strife' or 'church' (from 'cill' meaning 'church' with a diminutive suffix). The spelling Kylian gained popularity in the 21st century, likely influenced by French footballer Kylian Mbappé, though the name itself is not of French origin. It first appeared in U.S. records in 2005 and has risen steadily since 2010.
