The short answer
Blair is a name taken from a Scottish surname that Behind the Name derives from Gaelic blàr, meaning "plain, field, battlefield". It is pronounced BLAIR, rhyming with "air". In Scotland the name is typically masculine, but in the United States it became more common for girls in the early 1980s, shortly after the sitcom The Facts of Life (1979-1988) introduced a character named Blair Warner; after leaving the American top 1000 two decades later it was revived by Blair Waldorf of Gossip Girl (2007-2012). Blaire is a spelling variant. In the United States Blair ranked #169 for girls in 2025.
Meaning and etymology
Behind the Name gives Blair as "from a Scottish surname that was derived from Gaelic blàr meaning 'plain, field, battlefield'". The surname is listed as the name's root, and Blaire as an English spelling variant. The entry's real interest lies in usage rather than etymology: in Scotland Blair is typically a masculine name, whereas in the United States it "became more common for girls in the early 1980s" after the debut of The Facts of Life (1979-1988) and its character Blair Warner. Behind the Name says the name then left the American top 1000 about two decades later, only to be "resurrected by another television character", Blair Waldorf of Gossip Girl (2007-2012). Behind the Name lists the name under both Scottish and English usage.

Blair is one crisp syllable with a preppy, polished feel, an impression its two best-known television bearers did much to fix. It reads as tailored rather than frilly, which makes it a natural choice for parents who want a girls' name without a soft ending, and its Scottish surname origin gives it a settled, old-money undertone.
