In terms of popularity, Aidan rose in English-speaking countries in the late 20th century and remained common into the 2000s, with spelling variations influencing its rankings.

Notable bearers include Saint Aidan of Lindisfarne (c. 585–651), a Northumbrian missionary associated with the establishment of Lindisfarne Monastery.
