Meaning & origin
Keegan first appeared in U.S. birth records in 1965 and gained popularity through the 1990s and 2000s, reaching its peak rank of 173rd in 2008. Since then it has been falling in use, with its latest rank at 621st in 2025. The name's appeal as a modern Irish surname choice placed it among top states like West Virginia, Massachusetts, and Iowa. With a one-in-3,804 frequency, it remains a recognizable but less common pick, maintaining a strong, friendly sound.
Keegan is an anglicized form of the Irish surname Mac Aodhagáin, meaning 'son of Aodhagán.' Aodhagán is a diminutive of Aodh, the name of a fire god in Irish mythology, thus 'little fire.' The name has been used as a given name since the 20th century, particularly in the United States.
