Aisling is an Irish language feminine given name meaning "dream" or "vision".

[1][2][3] It refers to an aisling, a poetic genre that developed in Irish poetry during the 17th and 18th centuries.

[5] There are many variant anglicised forms of the name including Ashling, Aislin, Aislinn, Aislene, Ashlyn, and Ashlynn.

Aisling held steady in the top 20 girls' names in Ireland from 1984 to 1996[6] and is therefore often linked with the millennial generation in Ireland, most notably in the Oh My God What A Complete Aisling novels.

Ashlyn is also occasionally regarded as a modern name derived from both Ashley and Lynn.
