Darby

Meaning & origin

Darby is a name of Irish origin that has transitioned from a surname to a given name, most commonly used for girls in recent decades. Its first recorded use as a given name in the United States dates back to 1936, but it saw a significant rise in popularity during the 1990s, peaking in 1995. Since then, it has been on a steady decline, reflecting a trajectory of falling popularity since 1996. In 2025, Darby ranked 2564th with an incidence of 1 in 23,636 births, making it a relatively uncommon choice. The name is most frequently found in states like Ohio, Texas, and California. Its sound and style fit well with modern, unisex-leaning names, appealing to parents seeking a short, two-syllable name with a crisp, recognizable feel. Etymologically linked to the Irish Diarmaid, Darby carries a sense of heritage while remaining accessible in English-speaking contexts.

Darby derives from the Irish surname Ó Diarmada, meaning 'descendant of Diarmaid', where Diarmaid is an old Irish personal name meaning 'free man' (from dí 'without' + airm 'restriction') or 'without envy'. The name was later anglicized to Darby, influenced by the place name Derby in England. It transitioned from a surname to a given name in the late 19th century, particularly in Ireland and the United States.
