Meaning & origin

Deagan is a modern American coinage that entered U.S. birth records in 1997. It reached its peak popularity in 2009, after which its usage began a steady decline. In 2025 the name ranked 5,608, given to roughly 1 in every 106,755 baby boys. Deagan fits a trend of adopting surname-like names with an Irish-sounding cadence, though it has no documented Irish roots. Its trajectory has been falling since its peak year, and it has never been recorded in any U.S. state with enough frequency to appear in top-state lists. Families drawn to Deagan typically appreciate its distinctive sound and its resemblance to better-known names like Keegan and Reagan.

Deagan is a modern American coinage, likely formed from the popular sound elements 'De-' (as in Deacon or Dean) and '-gan' (as in Reagan or Keegan). It first appeared in U.S. records in 1997 and has remained uncommon, never cracking the top 1000 names. Its rise in the 2000s followed a trend of invented Irish-sounding surnames as first names.
