The short answer
Aiden is a masculine name that Behind the Name records simply as a variant of Aidan, pronounced AY-dən. Aidan in turn is the anglicized form of the Irish name Aodhán. Behind the Name attributes Aidan's late-20th-century popularity in America to its sound, which it shares with names such as Braden and Hayden; Aiden is the spelling that now leads in the United States, ranking #62 for boys in 2025. The meaning of the Irish root Aodhán was not verified in this pass.
