Meaning & origin

Keagen is a modern American coinage that first appeared on U.S. records in 1992. It reached its peak usage in 2008, with the number of baby boys named Keagen growing steadily through the early 2000s before beginning a gradual decline that has continued through 2025. Unlike traditional Irish surnames such as Keegan, from which it likely draws inspiration, Keagen has never cracked the top 1,000 names in the United States. Its spelling pattern with the -en ending aligns with modern trends, yet it remains relatively rare, with no single state reporting particularly high usage. Its trajectory classifies it as a falling name since 2008, suggesting it was a product of that decade's fashion for creatively respelled, soft-sounding boys' names.

Keagen first appeared on U.S. birth records in 1992, part of a wave of creative respellings and phonetic coinages that emerged in the late 20th and early 21st centuries. It may be derived from the Irish surname Keegan (from Ó hAodhagáin, meaning 'descendant of Aodhagán'), but the spelling <Keagen> is a distinctly modern American adaptation, likely influenced by the popular -en ending seen in names like Aiden and Jayden.
