Meaning & origin

Devlin is an Irish surname turned given name, rooted in the Gaelic Ó Dobhailéin, meaning 'descendant of the dark one' or 'fierce one.' Historically a clan name in County Tyrone, it entered the American baby name landscape in the late 1950s, with its first recorded use in 1957. The name saw a gradual rise in usage, peaking in 2007 before entering a steady decline; since 2004, its trajectory has been consistently falling, and as of 2025 it ranks 6,446, given to about 1 in 131,390 newborns. Though not associated with any particular top states in recent decades, Devlin retains a distinctly Irish character, often chosen by families seeking a strong, surname-style first name. Its nickname-friendly form and resemblance to popular names like Declan keep it within the orbit of contemporary Irish naming trends.
