Derived from the Gaelic word for “fire,” Aidan carries a spirited energy. It is not aggressive; rather, it suggests a warmth and brightness, much like the “little fire” its meaning implies. While it became the poster child for the “rhyming name” trend of the early 2000s, Aidan stands apart as the original, the authentic, historical choice with deep roots in monastic history and Irish royalty.
Verdict: Aidan is a fantastic choice for a baby born in 2025. While it has cooled from its fever-pitch popularity of the early 2000s, this is actually a benefit. It has graduated from “trendy” to “modern classic,” allowing your child to have a recognizable, beloved name without being one of three Aidans in the classroom.
Aidan Overview
- Meaning: The name Aidan has Gaelic origins and means “little fire.” Its roots are tied in Irish mythos to the Celtic god of sun and fire “Aodh.” Aidan was born from Aodh, or the given name “Aodhàn.” Over time, the variations ended up in their modern versions: Aidan or Aiden.
- Gender: Aidan is primarily a boy’s name. On occasion, it has been given to girls, but feminine variants such as Aidyn or Ayden are more common choices.

- Popularity: In the United States, Aidan was ranked number 261 in 2020. However, its variant spelling “Aiden” rose to 24 in 2020. That represents a substantial rise in popularity as it placed number 324 in 2000.

What Does Aidan Mean?
The name Aidan has Gaelic origins and translates directly to “little fire.” However, this definition only scratches the surface of its fiery personality. The etymology is a diminutive form of “Aodh” (pronounced ‘Ee’), the old Celtic god of the sun and fire.
In Irish mythology, Aodh was a name carried by numerous ancient High Kings and heroes, symbolizing brightness, energy, and spirit. By adding the diminutive suffix “-an,” the name becomes “Little Aodh” or “Little Fire.” It implies an inner warmth and vivacity rather than a destructive force. It suggests a child who brings light and life into a room.
Where Does the Name Aidan Come From?
Aidan is deeply rooted in Irish history and Catholicism. While it stems from pagan mythology via the god Aodh, it was solidified in history by the famous 7th-century monk, Saint Aidan of Lindisfarne. He is credited with restoring Christianity to Northumbria and founding a famous monastery. He was known for his kindness and compassion, traits that softened the “fiery” nature of the name.
The name remained a staple in Ireland for centuries. During the massive Irish diaspora to the United States, Canada, and Australia, the name crossed the ocean. It lay relatively dormant in the US until the late 20th century, when a cultural shift toward softer, vowel-heavy boy names brought it into the spotlight.
How Popular is the Name Aidan?
Aidan is a fascinating case study in American naming trends. It was virtually unheard of in the US prior to 1990. However, spurred by pop culture references and a desire for Irish heritage names, it skyrocketed in the late 90s and early 2000s.
It is important to note the trajectory: Aidan (the traditional spelling) peaked around 2003 but has since been overtaken by the Americanized spelling, Aiden, which became a top-10 hit. Currently, the name is cooling off. It is no longer the ubiquitous trendy name it was two decades ago, which is excellent news for parents in 2025. It has settled into a comfortable position as a familiar, well-liked staple that is neither obscure nor overexposed (1).
How Do I Pronounce Aidan?
The traditional and most common pronunciation is AY-duhn.
- The first syllable rhymes with “hay” or “say.”
- The second syllable is a soft schwa sound, often sounding like “dun” or “den.”
In its original Gaelic form, the pronunciation is very similar, though the “d” can sometimes be softer. In English speaking countries, there is virtually no variation in how this is said, making it a very easy name to live with.
Is Aidan a Boy or Girl Name?
Aidan is traditionally and predominantly a boy’s name. In Ireland, it is strictly masculine. In the United States, the spelling “Aidan” remains overwhelmingly male.
However, the trend of using surnames and Irish names for girls has led to some usage for females. When used for girls, parents predominantly opt for feminine-coded spellings like Aidyn or Ayden to differentiate it. If you are looking for a strictly female equivalent with the same roots, the Irish name “Aodhnait” (Little Fire) is the historical counterpart.
