Aisling is an Irish feminine given name meaning "dream" or "vision". It refers to an aisling, a poetic genre that developed in Irish poetry during the 17th and 18th centuries. There is no evidence that it was used as a given name before the 20th century. The name is included in Reverend Patrick Woulfe's 1923 collection of Irish names, with the comment that the name was in use in Derry and Omeath.
