Adair

Meaning & origin

Adair is a unisex name of Irish origin, first recorded in U.S. data in 1914. Its meaning is tied to the Irish surname Ó Dáire, referring to a 'descendant of Dáire' and often associated with 'oak grove' or 'spear wealth'. Despite ranking 2,145th as of 2025, with a rarity of 1 in 25,494 births, Adair has shown a notable upward trajectory, rising in popularity since 1987 and peaking in 2007. The name is most common in Georgia, California, and Florida, suggesting a broad but scattered appeal. Its sound fits well with contemporary surname-inspired names, offering a nature-infused yet strong option for any child. The lack of widely known famous bearers allows the name to feel fresh and personal, while its history provides enough depth for those seeking a name with roots.

Adair is an Anglicized form of the Irish surname Ó Dáire, meaning 'descendant of Dáire'. Dáire itself is an old Gaelic name possibly derived from 'dáire' meaning 'fruitful' or 'fertile', though it is also sometimes linked to 'doire' meaning 'oak grove'. The surname was brought to Scotland and England, where it developed into a given name in the 19th century. In some cases, Adair may also derive from the Scottish place name Eddair or from the English surname Adair, of Norman origin, meaning 'spear wealth'.
