Meaning & origin

Aileen, a name of Irish origin, has been in steady use in the United States since 1880. It reached its peak rank of 799 in 1926, reflecting its popularity during the 1920s. Today, it is less common, with approximately 1 in 4,727 girls receiving the name in 2025. The name has been most popular in states such as California, Texas, and Arkansas. While it shares roots with the more common Eileen, Aileen offers a slightly distinct spelling that has maintained a consistent presence over the decades. Its meaning, 'bright, shining light,' connects it to a rich Irish heritage, making it a recognizable yet uncommon choice.

Aileen is an Anglicized form of the Irish name Eibhlín, which itself is a Gaelic form of the Norman French Aveline, ultimately from the Germanic root aval, meaning 'desired' or 'wished for'. The name has been used in Ireland and Scotland for centuries, often associated with the mythological figure Ailill. In the United States, Aileen saw a peak in popularity during the 1920s.
