Keegan Name Meaning, Origin & Popularity
/ˈki.ɡən/
Meaning of Keegan: The name Keegan derives from the Irish surname Mac Aodhagain, meaning son of Aodhagan - a diminutive of Aodh, the Irish word for fire, ultimately derived from the Celtic god of the sun and fire. According to Etymonline, the Mac Aodhagain family was a prominent brehon (traditional Irish legal) family from County Galway and County Roscommon, known as custodians of Irish law from the medieval period. The anglicized surname Keegan developed as Irish naming conventions adapted for English administrative records.
The fire connection embedded in Keegan's Celtic root places the name in a category of Irish names with elemental meanings. Aodh appears in multiple Irish legends and genealogies, and Aodhagan - the source of Keegan - was a common given name in medieval Ireland before transitioning primarily to surname use. The fire symbolism carried associations of energy, passion, and spiritual connection across pre-Christian Celtic traditions.
Keegan entered American naming culture as an Irish surname-turned-given-name during the 20th century. The name gained visibility through actor Andrew Keegan (born 1979), who appeared in numerous 1990s teen films and TV series, and through Keegan-Michael Key, the actor and comedian who co-created "Key and Peele."
