Meaning & origin
Ailin is a rare but enduring name in the United States, first recorded in 1990. Its peak popularity came in 2012, and it has been gradually declining since 2011. In 2025, it ranked 3,712 with a 1-in-40,182 incidence, making it a distinctive choice. Top states for the name include Illinois and California. Ailin likely traces back to Irish origins, either as a variant of Aileen (from the Norman French Aveline, 'hazelnut') or from the Irish word for 'bright' or 'beautiful' (ailin). Its spelling gives it a modern feel while maintaining a traditional sound. Parents drawn to Irish heritage but seeking a less common alternative to Aileen or Eileen may find Ailin appealing.
Ailin primarily derives from the Irish name Aibhilín, a variant of Eibhlín (Eileen), which itself comes from the Norman French Aveline, ultimately from Latin Avellana (hazelnut). Alternatively, it may connect to the Irish word ailin meaning 'little bright one' or 'beautiful'. In modern usage, it is often treated as a variant spelling of Aileen.
